I have iTunes Match, and, I created a playlist on my iPhone, put a few songs in, and listened to it on the train. I get home, open up iTunes on my Mac and realize that the playlist was literally copied 10,000 times. I assume this is because it is the limit for the number of playlists you can have... Now, whenever I have iTunes match on, my music app crashes on my iPhone and iPad. I haves spent hours trying to delete them one by one (as there is no way to select multiple playlists) however they just return. I went to the Apple store and worked with a few geniuses for a couple of hours and the had no clue, so they had me call Apple support. I was on the phone with them for 3 hours, sent them photos, they even remotely accessed my computer (didn't know they could do that!) and played around with it. They had no idea, they gave me a number and said they would get back to me. Six months later, they still have no clue what to do. Has anyone else encountered a similar problem before? I assume this is an iTunes Match issue. Its a real shame because I paid for the service and it is literally making it impossible to use iTunes or listen to music anymore. Please help!
