Bought an Air 2 tonight, and am trying to get my magazines transferred over from my old iPad. They are working fine on my iPad 4 on iOS 8.1, but on my new Air 2, the magazine shows up on the newsstand shelf, but when I launch it it goes to the apps title screen for a second then just crashes back to the newsstand shelf. I've already uninstalled/reinstalled, no good. Do I need to do something with the old iPad subscription before it will show up on the new one? Is there some limitation to how many devices a magazine can be on?
