Paramount + Buffering/Freezing Unwatchable on TV with Cable Box

We are experiencing the same issues as other users in different posts with buffering/lagging/freezing when trying to watch P+ on the TV with a direct cable box input.  I've commented there, but no response.  Paramount+ always buffered the program at the start, but then you could watch it without interruption for the most part.  Not ideal for what you pay, but at least you could use the App. Beginning last week, the freezing occurs all throughout the program, making it unwatchable.  We've tried all the solutions, resetting the cable box, refreshing the signal and clearing the cache.  Those steps do not fix the problem.  I see in a different post that Comcast knows this is an issue.  The recommendation was to use a different device until it's fixed? That is an unacceptable response.  We are paying for the service and cannot use it.  There is also no update or timeline for a fix, so we don't even know if that statement is accurate.  Other streaming apps work fine, i.e. Netflix, MAX and Peacock.  We'd like a definitive answer on the issue, please. Is Xfinity not able to support Paramount Plus via the cable box?  Perhaps other service providers are better equipped to handle this particular streaming app.
