it's not that hard – FamilyFun Magazine Review

Although it did take me a time or two to get the email/password business to go through the ap, it certainly did not take an hour. The part that might trip people up is that you have to sign back in and this can only be done by clicking on "cover" at the bottom of the ap's main screen. It takes a bit of clicking around and isn't entirely intuitive, but once it's done, it's easy to download the digital additions. All my devices are fully updated and I'm not having any problems.
