Used to be great now the app won’t even open – NCLEX PN Mastery Review

I take the NCLEX in 9 days and this app has been an amazing study tool up until th latest update. Now my app won’t even open...it’s just a black screen. I can access the questions on a laptop thankfully but that takes the convenience right out of this app. I have restarted my phone and deleted and redone loaded this app and it still co tinges to do this. Fix it ASAP.
