Xfinity stream still down for my Samsung 2021 TV (Error:TVAPP-00148)

I haven't been able to watch xfinity stream after an update to it around Jan. 20.  I'm completely disappointed on how this has been handled.  On the day it went out, I wasted several hours over the phone with customer reps that were clueless on what was going.  Later I found on this forum, many people with Samsung tv's had the same problem, unable to stream live tv.  I finally was told by an Xfinity rep that they are aware of the problem and are working to correct it, and I would be contacted when it was fixed.  No one has reached out to me and I'm still unable to stream live tv on this Samsung.  A week or so ago, the error message changed from "This Video Cannot be Played (Error:TVAPP-00148)"  to "We're sorry.  Due to an issue with Samsung's firmware, we're currently working to address a problem associated with live TV within Xfinity Stream on certain Samsung 2021 TVs.  If available, please consider using an Apple AirPlay, Google Chromecase, Roku, Fire TV or Apple TV streaming device to watch on this TV.  You can also watch on your computer, tablet or mobile phone.  For more information, please call Samsung at 1-800-SAMSUNG (Error:TVAPP-00148).  How kind of Xfinity to update the error message, which by the way only lasted a few days and now displays the generic original error message when trying to stream.  I called Samsung and they were aware of the problem and are actively trying to fix it, and from what I got from the Samsung rep is that they feel it is Xfinity's fault.  So, I chose this service and tv a couple of years ago, so I wouldn't have to purchase a separate set top box or streaming dongle.  I didn't want to have more cords to look and worry about.  This 2021 Samsung of mine is in my living room, so I'm more than upset that what once worked fine, is now unavailable for several weeks.  I know I can hook up any of these devices that Xfinity suggests, but that would require me to not only buy it, but also an Electric outlet extender for the outlet on the wall behind the TV.  I refuse to have to do this since Xfinity can't get their act together.  If this isn't remedied in the very near future, I believe Xfinity will lose me as a TV customer, I will be forced to find some other provider that cares about supplying reliable good service.  I probably should have run for the hills along time ago.  

P.S. I'm wondering why Xfinity has closed the previous forums regarding this situation?  Guess they don't want you to see how [Edited: "Language"] people are over this.
