Hi @pumpe19 – thanks for the question, I had been planning to make a post about this today.
We recently fixed a bug that was causing our library of Tidal content to sometimes pick the wrong version during the process by which Tidal’s library is added to Roon’s database, matched to Roon’s metadata, and made available to appropriate regions. Because the wrong version was being selected, these albums were showing up as unavailable, but we’ve now corrected this issue.
Going forward, you generally shouldn’t see albums in Roon that are unavailable. The only way this should happen is if they were available in the very recent past, but have just recently been removed by Tidal. In that case, the album may temporarily show up as unavailable in Roon, and should also be unavailable Tidal’s website – if you’re seeing otherwise, we’d like to hear about it, except for one case…
If you’ve already added an album to your Roon library, the album may unfortunately be the wrong version, and will continue to show up in your library as unavailable. In that case, you’ll need to select the album (or all the tracks), delete the Tidal songs from your library, and re-add the correct version via Roon or the Tidal website.
Sorry for the trouble here folks!
