I have programmed a Firebase Notification App as described in the example. Only the Notifer I replaced with the NB6 Class and set StartAtBoot to True. Everything works fine so far and the app did exactly what I expected. However, after a while I noticed that my messages arrived with a few minutes delay when the phone was in stand-by mode. That's why I wanted to try KMatle's tip (link below), set the priority to HIGH and add a date.
Now I have found the following problem:
When the program is running and I receive a Firebase PN, the content of Message.GetData.Get("title") and Message.GetData.Get("body") is "NULL". So I only get an "empty" notification that only contains the date.
If the app is closed, I get a notification that contains the title and the body, but not the date. Any change to the notification will only affect the notification that is displayed when the program is running.
I also updated the app to use a receiver module instead of a service. But this has the same effect.
Could it be that a service is still running on the phone that intercepts my messages and displays them differently?
If so how can I delete the service from my phone?
I have already uninstalled the app and restarted the phone etc. But nothing has solved the problem.
In the app settings it also shows me two different notifications under "Settings->Notification". Once notifications with the name of the APP and once Miscellaneous. When I turn off the Miscellaneous permission, no more notifications are shown to me when the app is closed.
If I turn off notifications for the app (APP-Name), I no longer receive notifications when the app is in view.
Here is my code: (Receiver-Module)

Thanks for your help in advance.

KMatle's tip:
FCM messages/notifications: Use Phonewakestate to throw notifications without delay
I mentioned that my fcm messages arrive without delay (data messages), but throwing a notification (even with high priority) doesn't work all the time when the phone sleeps. Setting the phonewakestate before throwing the notification and releasing it after seems to work: pws.PartialLock...
