App crashes every time since update

Update 2: June 14, and several app versions later - this still happens!! -1 star

Update: no deals ever load any more. I just some error that says "this error is returned if the application is not registered in the eCP." So disappointing. Its probably cost me $50 at least in lost ability to use deals.
Tried uninstalling and reinstalling. Doesnt work.

App has become unusable on iPhone 7 since update. I was a daily user of the "deals" and now app just aborts 1 second after lauching.
