My Question or Issue
Will occasionally pause playback of songs - This can happen between songs AND sudden, mid-track, with the phone screen on AND off, and regardless of the app running in background or foreground (i.e. visible/open).
When this happen, not only do the notification bar controls disappear, but also controls on Lock screen and Always On Display disappear.
Even if I go on and start the app to resume playback (press play) - it will, appear to, behave normally. But I cannot control the app from the system notification, lock screen or AOD. It's as if the app is not running if not for the normal playback, playing track after track and responding to Bluetooth device controls.
Also it's like it is running on other audio channels.
Music won't dive/pause when e.g. another app plays audio/video, and if I disconnect my BT headphones or 3.5 Aux cable, music will sometimes keep playing, and other times (mostly) paus - only to resume playing 30-90 seconds later. Normal behavior used to be that it pauses until I decide to resume playback!
To work around this issue, each time playback stops, I open Spotify, bring upp recent apps, swipe away Spotify to "close" it, open Spotify again (I know it's a new instance because seeker is back at 0:00).
But I am getting tired of this, and it's not funny thing to keep doing when driving - especially not when music suddenly goes on playing in my pocket when I e.g. get outside my car...
