I all read this:

Automatic Foreground Mode

This is a new feature added in B4A v8.0. Starting from Android 8.0, services cannot be simply started while the app is in the background or not running at all. Background means that there isn't any visible activity or any service in foreground state (Service.StartForeground). Common cases...

FirebaseNotifications - Push messages / Firebase Cloud Messaging (FCM)

Updated tutorial: https://www.b4x.com/android/forum/threads/b4x-firebase-push-notifications-2023.148715/ Clarification: The nice thing about FCM is that your app doesn't need to run in order to receive messages. The FirebaseMessaging receiver will be started by the OS when a new message...

But after ~10 minutes when the app is in the background, no more notifications arrive.

If i set this to true, then at least notifications will arrive after i close the app via the manager, but after ~10 no notifications arrive.
FirebaseMessaging Service: 
#StartAtBoot: True

Do I have to use this instead of "StopAutomaticForeground"? Or what else must I do?

i found out that if the app did not close(in the background), notifications still arrive after 10 minutes. But how do I get them to arrive when the app is closed by the manager?

My parents for example press the "Close all" button when they put the phone away, but then notifications should still arrive...

You can try to schedule a service to check notifications at some time interval.

But ideally, I don't think there is a solution for that (I might be wrong). Even apps like WhatsApp don't display notifications when I manually close them.

If you close the app with the Close all method of the taskmanager then your app can get the status crashed on some devices.
Android prevent receiving notifications until the app is started manually once in this case.

TIP: Tell your parents not to use CLOSE ALL

Really?
I usually just manually close an app when I don't want to get any notifications from it and it works all the time.
I don't use FB though, and I also think it may vary from device to device.

While there are cases, mainly depending on the specific device, that messages will not arrive, the steps you did will not help.
