A few times, especially with new or just released (sometimes even unreleased albums), Roon finds albums or tracks on Tidal, but these tracks and albums cannot be played - you try to click and it says “No Play action available”.
Services always want to be the fastest and label/artists tend to allow some tracks in advance. But with this, the whole album does not play yet. Some albums are also only shown and never released for streaming. Buying from Bandcamp/Qobuz should be encouraged that way. I find the procedure dubious, but it has nothing to do with Roon. The problem is only visible there too.
Yes, it seemed is somehow related to the way labels/artists are publishing on Tidal.
But some music never becomes available. Somehow Roon finds it. Is frustrating at times.
I agree Bandcamp is the way to go for buyimg music.
