Glad to see some of you have found workarounds. Unfortunately, this is a long standing issue dating back to (at least) the changes made in version 1.8. I have brought it up in threads years ago here, as did someone else before me:
The real answer is, it’s not you, it’s Roon. Before 1.8, under the ‘appearances’ section on an artist page, there was a production section which would include anything from remixes, to engineering and so forth. This issue is still unresolved, and quite annoying if, like me, you listen to a lot of reggae or electronic music, it was nice to have all your remixes or all works of a producer in one spot (which was part of the reason I switched to Roon - it was so helpful how it pulled all of these things into one view).
Now for whatever reason, it seems to show up arbitrarily. I have the odd artist page that shows a production section, but 99% of them do not. I have wondered if it stems from the change to Valence, which seemed to ‘emphasize’ certain artists and credits the A.I. deemed relevant, and essentially not showing everything else. Which is baffling to me (like, how does King Tubby not get a production header??)
Anyways, good luck to you all…
