I'm not sure either. I had some issues with Tidal that signing in and out fixed. I still have an issue where I have a playlist on my phone and on the windows app that has more songs in it than shows on the R3. I have signed in and out and still won't show. It has a lot of songs in it about 150-160. I created a second playlist with some of the songs making the first playlist 107 or so songs now. The second playlist shows in my playlists on the R3 but the first one still only shows the original songs. Not sure if there is a limit to the amount of songs the R3 will show in a playlist?
