Stopped working b4 removed app access to TV provider – FXNOW: Movies, Shows & Live TV Review

Previously worked on my iPad with no issues. Now the app will not authenticate and responds: authN. AuthenticationFailure 029-1216-000. Tried deleting and reinstalling and updating to no avail. Contacted FXX customer care who advised the Apple single sign on sometimes blocks. When I removed and didn’t allow the app to access the TV Provider, all worked well again. Thanks for such a clear solution without making me jump through hoops as cable providers often do.
