I recently updated all my MP3 tags (using Mp3Tag) and all tags are now id3v2.4. When I re-index my Sonos library, the cover art no longer shows. I was able to verify this by reverting a few albums to id3v2.3 and, after re-indexing again, art for those albums’ covers showed up in Sonos.
Does Sonos not fully support id3v2.4? The other metadata seemed fine… just no art.
Thanks for any guidance!
