great app but there's just one problem... – Dot n Beat-Test hand speed Review

when it gave me an option to play my own song(s) i clicked it and watched and ad. It did nothing. It has nothing to do with the In App Purchases, and i think it just needs to be improved. that's the only problem I've found in this game. not major, but i like to play games with my apple music as well. thank u~ ??
