Ummm help? – Japanese by Living Language Review

I've used this app on other devices before and it worked perfectly fine, but I just got a new iPad and I downloaded it. It's being very glitchy and while on this app it will not let me interact with it, and what i mean by that is THE SCREEN ISN'T WORKING WHILE ON THIS APP!!!?!? I'm hoping that this problem will get fixed soon, but other then that I really liked it when I was using my other devices.
