Additional information

Messages are received after opening this client (moving to foreground).

Jami website states that ... using a permanent notification, to prevent the application from being killed (this is what the "Run in background" option in Jami has done). There is no "permanent notification" or any notification after turning on "Run in background".

When I developed an Android app that needs to run in the background, I had to use setForegroundAsync to keep it alive, calling this function also creates a notification. Maybe that's what Jami needs?
