Can you make screenshot of MMA on your phone (usually Power+Volume Down) and let us know what MMA version you use.

This is an odd one. I have two groups that are not displaying album art only in the Artists & Album Artists view. They display just fine in the Playlist view, which is the same format. It's not really a big problem for me but I just want to know if anyone else has had this issue and if they found a way to correct it. Thanks in advance.
