Do you want to sync your Qobuz playlists into Roon or do you want all your tracks/albums on Qobuz playlists to be added to your Roon library automatically? These are two different things.
Qobuz playlists should sync into Roon playlists automatically.
Adding Qobuz playlist tracks (that are not favorited on Qobuz) to the Roon library automatically, I don’t know. Maybe this is somewhat helpful?
