Someone I know built a Tidal playlist (Irish music). By clicking on a link I could open it in Tidal online, and then I was able to access it through the Tidal app. But–I’ve got Roon running on a headless server; it’s not so easy to access Tidal directly on my main system. How do I access that playlist in Tidal, via Roon?
In the Tidal app, try clicking on the star to favourite the playlist. After the next sync with Roon, it should appear in Roon’s playlist view.
