I can't seem to find information on this anywhere. Is there an Android app that I can use on my tablet for reading magazines for which I have an existing subscription? Everything I'm finding (Google Play Newstand, Zinio, etc.) seems to require purchasing a subscription but doesn't give an option for existing subscribers. FYI - I have a Nook HD+, but nobody uses that forum so I wanted to post in a forum people actually use. I've got Cyanogenmod loaded onto it so it's straight-up Android 4.3.1.
