This was given to us as a gift, and we can't even use the app. Kid was very excited about this, we opened the book and she selected the picture she wanted to color. She colored it while I downloaded app.
Once I opened the app, only one page is "unlocked", and of course it wasn't the page she colored. It says to register, but every time we try with the code we found inside the book, it says "registration failed."
She hasn't been able to use the VR portion at all, and this was a birthday gift. Basically a $25 coloring book.
