Broadcast (CBS, ABC, etc.) stream apps no longer working with Xfinity

As of this past weekend, have encountered error messages whenever I try to watch live TV with my normal streaming apps, such as CBS and ABC. I have never encountered this before. It says that the live stream is not available through Xfinity.

This is extremely frustrating as these apps have been the only way that I have been able to watch sports since the Xfinity Stream app has been glitching nonstop all season long.

Why are the normal broadcast live streams no longer available through Xfinity when we are still being charged broadcast TV fees?

How many others are experiencing these issues?

Xfinity needs to refund customers for consistent lack of service and fix the system once and for all.
