I am trying to turn On the Automatic Downloads for music, apps & books from the Store setting on my iPad 2. However, when I click to change the settings from off to on, it automatically switches back to off. I have an iPhone 4S & it works fine, but I can't get my iPad 2 to do the same. Also, when I go on iTunes via my laptop, my iPad is not listed as one of the managed devices for my apple id. It only shows my iPhone & my laptop. Any suggestions?
