AP DOES NOT WORK OR ALLOW ME TO SIGN IN!!! So mad right now – Navigate eReader Review

This ap doesn't work, doesn't let me sign in, doesn't let me use ebook without using the ap on my iPad. This was the reason I got this book and I can't even use it. This needs to be fixed or return my money for my book because that is false advertising. If I'm doing something wrong it is certainly not obvious. I've had the same JB learning sign in for years and I've tried to launch through safari as it instructed and it made no difference. Fix this..IT'S USELESS. Don't count on using this if you up the books!
