My iOS 6 (on iPad2) issue of the day:
I'm trying to re-download my purchased music and other than 6 tracks that the iTunes store wanted me to re-authorize by pretending to re-purchase them, it went okay except for one REALLY annoying thing. I can not get a download option for six releases from one artist that I have already purchased. The purchased tab shows the artist but tapping that just brings up the infinite spinner. If I go to the store and view those releases, none of the tracks have the download button, just the price/purchase button.
BUT if I use my iPhone 4 running iOS 5.x (jailbroken) and go to the purchased tab (where I can actually search within just the purchased, not so with iOS 6 which forces you to browse), the exact same releases show up as downloadable.
Bah.
I've rebooted the iPad and have signed out and signed back in on the iPad. No joy
