I have a large library of mp3 and flac files with album art encoded using ID3 tags. The album art displays fine in the Poweramp app and in the menus of Poweramp in android auto, but not in the main song screen of android auto. I can, however, get the art to display for an entire album in the main screen if I go into the app and manually set the album art for one song on that album to the embedded art.
I can reproduce this bug in both my android auto head unit and the android auto app.
