App is now unusable since iOS update along with newest version

Even with version 9.6.2 and many attempts to reinstall app it continues to crash on IPhone 6plus and IPad Mini 2 and when it does open to test questions shows a blank screen no questions whatsoever.
Have attempted to resolve through support. No luck!
Hopefully gets resolved soon, was a great app.
