TV Provider Login not working after update – IFC Review

I can’t use the app to watch Brockmire if I can’t sign-in using my Cox account. What happened? When I select Cox as my provider, I get the login form, which I fill-in, click the “Sign In” button - then completely blank screen that I can’t get out of. My only option at that point is to click the < (back) button.
