Encountering TVAPP-00209 on Xfinity Stream app

This began on Sunday Oct 11 around 10:00 am CDT.  I get the error code when trying to launch a TV program from the Stream portal (xfinity.com/stream).  I get the error message when trying to launch a TV prog from the Live TV menu option.  I also get a TVAPP-00309 code if I try to launch a tv prog saved on the dvr.  I am able to launch older progs that have been saved (some prior to 10-11-26, but not all).

The device I used is an HP Chrome book (Chrome OS), but I have also tried on Two HP Windows Devices (Windows 11), along with two samsung android phones, all to no avail.  I have switched networks, cleared cache, cookies, and browsing history, multiple reboots, cold boots, and all the standard debugging procedures I can think of.  I see from this forum, that others are experiencing the same problem.   Please let me know if I can provide any additional information.  Thanks
