Awful App. No point in it at all, unless you want your children to have your device and not Thier own. If installed on a child's device, you cannot subscribe. Read an earlier response to a review saying it's a fault with Google. NO ITS A FAULT WITHIN YOUR PROCESS. What's the point in having a enterable code in your app if you don't make sure of it, especially in this scenario. Poor design and poor execution.
