Why Are Notifications Not Showing Up on My iPhone After the iOS 18 Update?

If you’re not getting notifications after updating to iOS 18, it could be due to some initial software bugs or glitches. New iOS updates often introduce minor issues that can interfere with normal functions, such as notifications. These problems usually get fixed in later updates. In the meantime, here are some helpful solutions to restore your notifications.


10 Ways to Fix iPhone Notifications Not Working After iOS 18 Update

Try these methods to resolve notification issues on your iPhone:


1. Check App Notification Settings

Make sure the app has permission to send you notifications:

  • Go to: Settings → Notifications.
  • Select the app that’s not sending notifications.
  • Toggle on Allow Notifications.
  • Choose your preferred banner style and ensure Sound and Lock Screen options are enabled.

2. Check In-App Notification Settings

Some apps, like WhatsApp or Instagram, have their own notification settings. Ensure these are set up correctly:

  • Open the app and navigate to its Settings → Notifications.
  • Adjust the notification preferences within the app.

3. Enable Notification Center on Lock Screen

If notifications aren’t showing up on your lock screen, you might have disabled the Notification Center:

  • Go to: Settings → Face ID & Passcode.
  • Toggle ON Notification Center.

4. Restart Your iPhone

Restarting your device can often clear temporary glitches:

  • For iPhone 8 and newer: Press and hold the volume up/down button and the power button until the slider appears.
  • Drag the slider to power off. Wait 30 seconds, then turn the phone back on.

5. Ensure Focus Mode is Turned Off

Focus Mode can silence notifications. To disable it:

  • Go to: Control Center.
  • Tap and hold Focus and select the active Focus Mode to turn it off.

Make sure automatic activation is turned off to prevent it from turning on unexpectedly:

  • Tap the three-dot menu next to Focus Mode → Settings.
  • Go to: Smart Activation or Custom Schedule → Delete Schedule.

6. Disable Share Across Devices

Focus Mode might be syncing across your Apple devices, which can impact your iPhone notifications:

  • Go to: Settings → Focus.
  • Toggle off Share Across Devices.

7. Turn Off Notification Summary

The Scheduled Summary feature could be causing delays in notifications. To disable it:

  • Go to: Settings → Notifications → Scheduled Summary.
  • Toggle off Scheduled Summary.

8. Enable Background App Refresh

If Background App Refresh is turned off for certain apps, notifications may not come through:

  • Go to: Settings → General → Background App Refresh.
  • Set it to Wi-Fi & Cellular Data.
  • Enable it for the apps you want to receive notifications from.



9. Disable Low Power and Low Data Mode

Both modes limit background processes, which can lead to delayed notifications:


For Low Power Mode:

  • Go to: Settings → Battery → Toggle off Low Power Mode.

For Low Data Mode (Cellular):

  • Go to: Settings → Cellular → Cellular Data Options → Data Mode → Turn off Low Data Mode.

For Low Data Mode (Wi-Fi):

  • Go to: Settings → Wi-Fi → Tap the blue i icon next to your network → Turn off Low Data Mode.

10. Wait for an iOS Update

If none of these solutions resolve the issue, it might be a software glitch in iOS 18 that will be addressed in a future update. Make sure your iPhone is up to date:

  • Go to: Settings → General → Software Update.
  • Tap Update Now if a new update is available.


These troubleshooting tips should assist in restoring your notifications after updating to iOS 18. To keep up with ongoing software fixes, always ensure you’re using the latest iOS version.
