Instagram notifications stop arriving for three main reasons: your phone's settings are blocking them, Instagram's app settings have them turned off, or your account has a technical glitch

The most common culprit is your phone's operating system, not Instagram itself. Both iOS and Android let you control notifications at the system level, which overrides what any individual app wants to do. If your phone is set to Do Not Disturb, has notifications disabled for Instagram specifically, or has Instagram in a restricted battery mode, you won't see alerts even if Instagram is trying to send them.

The second layer is Instagram's own settings. The app has separate controls for different notification types — comments, likes, messages, story replies — and you may have turned off the ones you care about without realizing it. The third possibility is less common but real: Instagram's servers may have stopped sending notifications to your device due to a sync error, which usually clears itself within a few hours but sometimes requires you to reinstall the app.

Key Takeaways

  • Check your phone's notification settings for Instagram first, because your operating system can block notifications even if the app is set to send them.
  • Open Instagram's settings and navigate to Notifications to confirm each notification type you want is actually turned on.
  • If notifications are on in both places, try logging out and back in, or reinstalling the app, to fix a sync error between your device and Instagram's servers.
  • On iPhone, check whether Instagram is in App Library or has Focus modes that silence it; on Android, check Battery Saver and app permissions.

Check your phone's notification settings first

Your phone's operating system sits above every app and can silence notifications even when Instagram wants to send them. Start here because it is the fastest fix.

On iPhone: Open Settings, scroll to Instagram, and tap it. Make sure "Notifications" is toggled on. Then check whether you have a Focus mode active — swipe down from the top right corner to see Control Center. If you see a Focus mode (like Do Not Disturb, Work, or a custom one), tap it and check whether Instagram is silenced in that Focus's settings. Also scroll down in Instagram's notification settings and confirm "Allow Notifications" is on.

On Android: Open Settings, go to Apps or process Manager, find Instagram, and tap Notifications. Make sure notifications are enabled. Then check whether your phone is in Do Not Disturb mode — swipe down from the top to see Quick Settings. If Do Not Disturb is on, tap it and check whether Instagram is in the exception list (apps that can notify you even in Do Not Disturb mode). Some Android phones also have a Battery Saver or Power Saving mode that restricts notifications; check Settings > Battery to see whether that is active.

Verify Instagram's notification settings

Once your phone is set to allow notifications, check Instagram itself. The app has granular controls for different notification types, and you may have disabled the ones you actually want.

Open Instagram and tap your profile icon in the bottom right. Tap the menu icon (three horizontal lines) and go to Settings and Privacy, then Notifications. You will see categories like Comments, Likes, Messages, Story Replies, and Reminders. Each one has its own toggle. Turn on the notifications you want to receive. If you want notifications from specific people only, Instagram also lets you customize notifications per account — go to a person's profile, tap the three dots, and choose Mute or Notifications.

Pay attention to the difference between push notifications (alerts that appear on your phone's lock screen or home screen) and in-app notifications (alerts you see only when Instagram is open). If you have push notifications off but in-app notifications on, you will only see alerts while you are actively using the app. Most people want push notifications on so they see alerts even when Instagram is closed.

Sign out and back in to fix a sync error

If notifications are on in both your phone settings and Instagram settings but you still are not receiving them, Instagram's servers may have lost sync with your device. This is rare but happens occasionally, especially after a major app update or if you have not used the app in several days.

The fastest fix is to sign out and back in. Open Instagram, go to your profile, tap the menu icon, scroll to the bottom, and tap Log Out. Wait a few seconds, then log back in with your username and password. Instagram will re-sync your notification preferences with its servers. If that does not work within an hour, try uninstalling and reinstalling the app — this clears out any corrupted data on your phone and forces a fresh read from the App Store or Google Play.

Understand Instagram's notification limits

Instagram intentionally limits some notifications to reduce spam. For example, you will not get a notification for every single like on a post if it gets hundreds of likes — Instagram groups them and sends you one alert instead. Similarly, if someone you do not follow comments on a public post, you may not be notified depending on Instagram's spam filters.

You also will not receive notifications if your account is restricted or if you have restricted the other person. If someone has restricted you, you can still see their profile, but they will not see your activity and you will not get notifications about their posts or stories. If you have restricted someone, you will not be notified about their activity.

Check whether Instagram is muted or restricted on your phone

Some phones have app-level muting or restriction features that sit between your phone's notification settings and the app itself.

On iPhone: Check whether Instagram is in App Library (the last screen when you swipe left through your home screens). Apps in App Library do not send notifications by default. If Instagram is there, drag it back to your home screen. Also check Settings > Notifications and scroll through the list to make sure Instagram is not set to "Off" or "Scheduled Summary" — it should be set to "Time Sensitive" or "Persistent" if you want real-time alerts.

On Android: Some phones have a "Notification History" or "Blocked Notifications" section in Settings. Go to Settings > Notifications > Notification History and check whether Instagram notifications are being blocked or delayed. If they appear in a "Blocked" section, tap it and re-enable notifications for Instagram.

What to do if notifications work again but then stop

If you fix the problem but notifications stop working again within days or weeks, the issue is usually one of three things: your phone automatically turned on a battery-saving mode, you accidentally turned off notifications in Instagram or your phone settings, or Instagram pushed an update that reset your notification preferences.

Set a reminder to check your notification settings once a month. If you notice notifications have stopped, go through the steps above in order — phone settings first, then Instagram settings, then sign out and back in. Most of the time, one of those three will have changed without you realizing it.

Frequently Asked Questions

Why am I not getting notifications for messages but I am getting them for likes?

Instagram lets you control each notification type separately. Open Instagram, go to Settings and Privacy > Notifications, and look for "Messages" or "Message Requests." Make sure the toggle is on. You may also have muted notifications from a specific person — go to your DMs, swipe left on their conversation (or long-press on Android), and tap Unmute.

Do I have to reinstall Instagram to fix notifications?

Not usually. Try signing out and back in first — that fixes most sync errors in under an hour. Reinstalling is the next step only if signing out does not work after a few hours. Reinstalling takes longer but clears out any corrupted app data that might be causing the problem.

Will turning on notifications drain my phone's battery?

Notifications use very little battery. The battery drain comes from your phone's screen turning on when you receive an alert, not from the notification itself. If you are worried about battery life, turning off notifications will not make a meaningful difference — lowering your screen brightness or closing background apps will help much more.

Can Instagram see that I turned off notifications?

No. Instagram does not know whether you have notifications on or off. The setting is stored on your phone, not on Instagram's servers. People who post will not see any indication that you have muted their notifications.

Why do some people's notifications come through but others do not?

You may have muted notifications from specific accounts. Go to their profile, tap the three dots, and check whether "Mute" is turned on. If it is, tap it again to unmute. You can also mute just their stories or posts while keeping notifications on for messages, which gives you more control over who you hear from.
