This is exact timing of my other issue, which is all my local library albums have disappeared as of the latest 1223 update. As of then, my Playlist track titles are now unavailable, regardless of local or Tidal file
I added my iTunes playlists and music files without difficulty but now a number of tracks are listed as unavailable even though they are still in my storage files unchanged in location from prior to the iTunes additions.
The “unavailable” tracks are all in Roon playlists that were created from flac and cd ripped files prior to importing iTunes. These are in flac files that i own - i don’t use Tidal or any of the other streaming services. Not all of the files are listed as unavailable but all the unavailable files are all in Roon playlists. I don’t see any “unavailable” tracks in iTunes playlists.
