I didn't notice it. Moving to receivers improved reliability.

The permission is requested by the OS (on Android 13+) devices. Try to uninstall the app and install it again.

Thanks for answer!

I did it several times, but always the same. On the fold 3, the system sets the notification after new installation to not allowed. The fold 3 has Android 13. I set the targetsdk to 31. Could this be the problem? From 10 installations, the fold 3 asked me two times to allow the notification after a few app starts, not all the times.
When the user sets the permission for notification in the settings of the app, the notifies will arrive reliably.
On an Galaxy A53 with android 12, the notifocation is set to allowed and there are no problems.

I also think I found that the receiver is not always started from the beginning after installation. It could be, that the starter-service tried to call the 'Public Sub SubscribeToTopics' in the FirebaseMessaging-Receiver, but does not reach it. So there are more than one app-starts needed to subscribe to topics. But maybe I got it wrong.

Once it is approved it shouldn't be asked again.

Sorry, then we misunderstood each other. After each complete deinstallation and new installation, the system only asked me twice for permission out of the 10 installations. In principle, this should happen after every new installation that has been uninstalled beforehand.

Now i made some more tests. The Galaxy A53, which worked fine under Android 12 get's an update to Android 13 and after that, there are the same different behaviors as under the galaxy fold 3:
After the fist app start (after installation), the notification is set to not allowed by default. Only when a message arrives, the app asked the user, whether it is allowed or not. So the first message will not show an notification and it is a strange behavior, since the query may not come until days after the installation.
This is the behavior, when the targetdk is set to 31.
I made round about 50 installations and deinstallations and a few times, the app asked for permission only one ore two times at the first start of the app, all the other installations, the permission is asked after the first push arrives.

If i set the targetsdk to 33, the device does not asked if notifications are allowed and under settings there is no entry for notifications. So it is not possible to set it manually. The app also is not able to receive notifications under Android 13 and targetsdk 33.
(All messages will be arrived in Sub fm_MessageArrived (Message As RemoteMessage) in the logs. But not possible to set a notification.)

But as said, only under android 13.

You shouldn't yet set the targetSdkVersion to 33. It requires some configuration. It will be available in the near future.
