for apps such as snapchat my notifications arent coming through(banners) or there isnt a little number on the app. I have to literally go onto the app and refresh it. Any ideas?

Hey itscaitlinhaywood98,

Thanks for the question. I understand that you are experiencing issues with Notifications for a few applications. The following resource may provide a solution:

Troubleshooting notifications

Push notifications require an active Wi-Fi or cellular connection.

Note: Notifications use Wi-Fi only when a cellular connection is unavailable. Firewalls and proxy servers may affect your ability to receive notifications. For more information, see Unable to use Apple Push Notification service (APNs).

If you're not receiving notifications for a specific app, try these steps:

1. Verify that the app supports notifications.

2. After installing an app or restoring a backup to a different iOS device, open the app to begin receiving notifications. If the app requires entering or logging in to an account, you will need to do this before receiving notifications.

3. Check Settings > Notification Center to ensure that the app is configured for notifications. If notifications do not appear in the Notification Center, verify that the Notification Center setting for the app is enabled.

Also, power cycling your device may help:

Turn your iOS device off and on (restart) and reset
