Following the recent Android Oreo 8.0 update, all my Google Play Music playlists are listed as 0 tracks. I don't understand how a system update would change a application like Google Play Music. Does anyone else have this problem and is there a way to restore playlists that have been deleted? In my case, this represents many hours of creating playlists for more than 400 tracks. I desperately need a solution as apposed to re-creating each list again manually.
