I can't seem to find information on this anywhere. Is there an app that allows users to view their existing magazine subscriptions on an Android tablet (in this case, the Nook HD+)? Everything I've tried (Google Newstand, Zinio, etc.) seems to only allow me to make new purchases. I'd really like to be able to view my existing subscriptions. I have several in print format, and at least some of them allow me to switch them to a digital subscription.
