how come that i am not receiving any messenger and fb push notifications? help

Greetings iammay14,

Welcome to the Apple Support Communities!

I understand that you are not receiving notifications for some applications on your iPhone. To troubleshoot this situation, please read over the information in the attached article to ensure the notifications for these applications are set up correctly.

About Notifications on iPhone, iPad, and iPod touch - Apple Support

Not getting notifications for a specific app

Push notifications require an active Wi-Fi or cellular connection. If you’re not getting notifications for a specific app, try these steps:

1. Go to Settings > Notifications to verify that the app supports notifications. If notifications do not appear in the Notification Center, make sure that the Notification Center setting for the app is enabled.
2. Make sure you’re signed in to your Apple ID.
3. If you’ve recently installed an app or restored a backup, open the app to start getting notifications.

Cheers,

Joe
