I am a long time user and now subscriber to Djay for iOS. My music is all DRM free in Apple Music. I download it to my iOS device where it plays in Djay with no issues.
I’ve recently tried using Smart Playlists in Djay. It works great when I filter on the Genre or Artist field. When I try using the Grouping or Comments field, I get no results.
Those tags are clearly showing as populated in iTunes. This may be a bug, but I’m open to any suggestions as to how I could check or get this working.
