iOS Training cards app not working . . .

Has anyone had problems with the Training Cards app in iOS?
Like locking up? or Not completing initial log in?
Do you get the “White screen of death” - no questions posted after initial log in?
I have been waiting for the updated version and was told it is posted to the App Store, so I downloaded it and it does not work. All I get is the “white screen” & it locks up.
I deleted the app, checked for the latest iOS update, rebooted & then reinstalled the app only to get the “white screen”:frowning:

I have the same problem.
