I have been using iTunes Radio since last week (love it, by the way), but yesterday it stopped working on my iPad. It continues to work fine on all my other devices (2 Macs, AppleTV, 2 iPhones), but on my iPad it attempts to play a song, fails to start, and then shows a message "iTunes Radio Unavailable. iTunes Radio is temporarily unavailable. Try again later". I tried to restart the iPad, turn it off etc. but the problem continues. I also tried to sign out of iTunes Match, from the iTunes Store, and it didn't help either. Any ideas, anyone?
