Another update: I now see that the changes were made on purpose:
I think that the changes are good overall and that they represent some significant improvements. But so far I haven’t figured out an efficient way to rebuild my organizational system for playlists in the new Roon system. I have 6,880 playlists made in Qobuz, which were previously easily accessible in Roon bookmarks. I hope I don’t have to just start over.
