Xfinity Now Streamsaver not showing live channels

Hello I have been having an issue with the xfinity stream app since Saturday. None of the live channels that are listed in the channel line up are showing ex: TLC, Revolt, Lifetime, MTV and etc. The only channels showing say TV go. I have deleted the app and signed out on tv, iphone and on a tablet with no luck. I have contacted chat and spoke with 5 reps with no assistance please help!
