Source-checked About 10 minutes

Answer

Check that the affected app is allowed to send notifications, then review Focus, Scheduled Summary, and the app's notification delivery settings. A delayed alert can be caused by a configured iPhone setting.

Check the affected app's permission

Go to Settings > Apps > [app] > Notifications and turn on Allow Notifications.

Review alert delivery

Check the app's sound, placement, and appearance settings, then look for Focus or Scheduled Summary settings that may delay delivery.

Test one app at a time

Send a non-sensitive test alert after changing one setting so you can identify which setting caused the delay.

Send a timestamped test alert to the affected app while the iPhone is locked and verify its arrival time after each single setting change.

If it does not work

  • If only one app remains delayed, update it and review its own notification and background settings. If all apps are delayed, record Focus, network, battery, and iOS state for Apple support.
