Xfinity stream missing local TV GO channels

NBC and CBS specifically is missing from the TV Go lineup on most of my devices either in the app on firestick, ipad and android phone or web browsers on PC and Mac. NBC comes and goes for the most part but today it has been gone. CBS has been gone for years. I am using all these devices out of home and on the same network where I am currently. I have done all the resets, uninstalls and reinstalls, cleared cache and data, reset the network, etc. and there is no change. This has been an ongoing issue that really need to be fixed.
