iOS 13 Music App album art is incorrect.
I've got an iPhone XR and just upgraded to iOS 13. I go to the Music App and the album art is associated with the wrong playlists for about 1/3 of the library - and when I close and reopen the app, the incorrect pairings of image to file has shifted (example: the album cover for a U2 album was showing for a YES album the first time, now the U2 album has the correct cover, but a Talking Heads album has the art work for a Dave Brubeck album...etc.)
I have rebooted the phone, re-synced the music library on the phone, even removed all of the playlists, etc. and re loaded them and the issue remains.
