Hello and welcome to Apple Support Communities, deniss86!
I understand you're not getting notifications for certain apps. I'd b happy to provide information to help you troubleshoot this.
Use the steps in the following article: Use notifications on your iPhone, iPad, and iPod touch
"If you don't see notifications for a specific app
To get notifications, connect to a Wi-Fi or cellular network. If you still don't get notifications for a specific app, try these steps:
- Make sure that the app supports notifications. Go to Settings > Notifications, select the app, and make sure that Allow Notifications is on.
- If you have notifications turned on for an app but you're not receiving alerts, you might not have Banners selected. Go to Settings > Notifications, select the app, then select Banners.
- Make sure that you’re signed in to your Apple ID.
- Make sure that Do Not Disturb is off.
- If you’ve recently installed an app or restored from a backup, open the app to start getting notifications."
Thank you for using Apple Support Communities.
Enjoy your day!
