I downloaded the Ubuntu Music app for android (running v.2.2) and all was going well... I had no problems uploading a couple albums to my "cloud" and then accessing them in the music app, but suddenly it seems like the app won't read the tags on my files and every new file is classified as "unknown artist" on "unknown album" even though I have double checked that the files were tagged correctly.
Is this a known problem? Is any format of tagging specifically not supported?
