Bluetooth still too flaky with car stereo

Hello, i know this has been closed

and i marked a solution, but the bluetooth is still so flaky is driving me crazy

First of all, i need to play a song first, then connect the bluetooth
Song should be played on one player exclusively, as if i play a song on the default media player and then switch to unplayer or bandcamp neither works, only the first one opened, and sometimes after several bluetooth restarts

Media from native browser instead, or webview does not work at all even with several restarts

As always no problems at all with my sony bt headphones

Just hoping this will get a little love :slight_smile:
