Since Friday I'm having this error message erveryday :
"A subscription is required to watch this channel.
Please call 1-800-XFINITY to add it to your service.
Everytime I'm asking an agent to fix it and everytime they just seem to refresh to fix it.
Am I doing something wrong when I connect or something else?
I'm using chrome on a laptop.
Thank you very much for your help.
I'm having the same problem after subscribing to STARZ, tech support agent couldnt solve it, and had to schedule a call back advanced tech or something but while i was waiting on the call back I discovered a band-aid fix to my error TVAPP-00401 issue.
Goto https://www.xfinity.com/stream/settings/playback-preferences and change Best Play Available to OFF. Then go try an watch a stream and select TV GO option not SD/HD
It worked for me.. temp fix at least until the root cause can be resolved
