Iphone doesn't show me anymore notifications from banks, trading site

Hi all.

I've an Iphone 13 Pro Max with IOS 17.6.1.

For a few days now, the notifications for accessing the apps of my banks and my trading account have no longer appeared. Instead, apps from other apps regularly appear (news, weather, whatsapp, calendar, etc.).

I checked settings - notifications and the banking apps have all notifications set "active". I tried resetting the network settings but that didn't fix the problem. I tried turning the iPhone off and on again but it didn't help. I also tried uninstalling and reinstalling the banking apps but the problem wasn't solved.

What else can I do?

Thank you very much
