iOS TV Remote app will not allow singing in with Comcast Business credentials

[TheDuckInn]

I can't get the Comcast remote app on iOS to accept our login and password. 

I've searched for solitions for a half hour but can't find anything except posts with the exact same problem from 4 years ago that remain unsolved. 

Help?
