I can see and play from my play Playlists (see some of them on my Screenshot below). But I can not add tracks or albums to my Playlists (see another Screenshot). I does not matter if the music is on my hardrive or from Tidal, I cannot add them to my Playlists.
Just found out, if I make a new Playlist, I can add music to this Playlist, but not to the old Playlists
Are the playlists you cannot add to ones you imported (such as m3u) or are they ones you created in Roon?
They are created inside Roon
Still the same issue with the playlists. I can see my old playlist, and can play them. BUT I cannot add music to the old playlists. I can make a new playlist and add music to it. But I want to add music to my old playlists. Am I the only one having this issue?
Hey KnockKnock, Did you end up sorting this out. Just started happening to me. Any fix suggestions. Cheers
No, and now I use Audirvana, much easier. You can even add to Qobuz playlist (not within Roon). The sound is also way better 
Hey,
Thanks for the quick response.
Yeah… I ended up just deleting all my playlists and starting again. very annoying.
I appreciate the advice.
Cheers
Alex
