When listening to live streams in background mode or with the app minimized AND the screen off (lock screen), the live stream stops after about 10-30 seconds. This happens during Rumble live streams but not YouTube live streams. Curiously it starts working again when you press the lock button on the phone and then stops again when it goes dark. After this it randomly plays for a few seconds then is quiet for a long time over and over. Watching Rumble live streams with the screen on is smooth and reliable with no dropouts.

All limits for app background use and power use are disabled. Batter saver is also disabled.

Does this problem still exists? I can't reproduce it!
