Since I updates to ios 6 a couple weeks ago,I've noticed that the music app is acting weird. It won't load album artwork properly,even though it shows in iTunes ,if I press a song and quickly exit it won't play until I re enter the app even tho the play triangle is in the status bar. and the biggest issue is home sharing,which will cut off my songs in the middle of it,& sometimes will start in the middle too,and my wifi connection is fine. I've tried several hard resets but to no results. Has anyone else had these problems or is just ios 6 running poorly on my iPhone 4?
