My media player that streams music disappears from the bottom left side of the screen and sometimes appears on the top right side of the screen and occasionally disappears altogether unless I keep the streaming app in the front. It disappears as soon as I switch to maps or any other app. Only way to bring it back is to reboot the computer which is annoying while I am driving. Any remedy for this weird problem? Tesla has done a bad job with the media player. Its getting worse!
