I woke up this morning and TCM is gone and asking me to upgrade xfinity package. I haven’t changed anything so why is it removed?

The error showed up and it is not going away. Xfinity has no information on this. I’m about to really cancel my account. I see some people had the same issue but Xfinity doesn’t want to display the solution publicly and each time they ask users to contact privately. Why not post the solution here?
