Useless after update Constant error message saying In App purchases not supported even though I own the books.Unable to access my books since the update.App doesn't even work correctly now. Contacted the developer and received absolutely no response.
Bought some book, had problem in my tablet, lost everything, when install everything again, i don't have access all my book, need buy all again!!
Update to previous rating Developer has been very helpful in trying to get this app to work on my Asus TF700. To date, we've been unable to solve the problem of why the app will not allow me to use Google Wallet to purchase. Rating adjusted to compliment the effort being made.
