I am having difficulty playing most of the genres from the genres page. The genres page loads fine, but when I click on the play button nothing happens. Some of the genres will play, most will not.
Have you made any edits to this content in Roon?
Not that I am aware of?
Is the album identified in Roon?
Not an album. A whole genres.
Is this content from local files, TIDAL, or Qobuz?
It all depends on the content of your library. A genre needs to contain playable content (Albums) for you to be able to play that genre, but many (most?) genres just contain artists (and artists aren’t playable content).
On my homepage there is a section labeled “Genres for you” which contains only a small subset of all the genres accessible through the genre browser. From this subset, all contain content and are playable for me. Is this different for you.
