At some point, all the tracks in at least three playlists have gone missing. Others are fine.
I recently upgraded to MC22, not sure if that's when it happened or what. In the process, I had to restore from a previous version backup because the MC22 install didn't automatically convert/copy the database.
Is it possible to import/restore playlists from an old backup, or is there some other way I might recover these playlists?
