Prior to using Roon I had created a number of playlists on Tidal. All of those playlists appear in Roon.
But… when I am in Roon (as opposed to Tidal) and try to add a song or album to a playlist, Roon only offers two playlists for me to add the song to. I can create a new playlist but what I am trying to do is add the song/album to a playlist that Roon already knows exists – but does not offer me as a choice.
The result is I have to open Tidal, find the song and add it to the existing playlist there.
