Xfinity message that system is not compatible

[bcreighton7]

Hi. Just yesterday, while trying to stream, Xfinity gave me a message that my system was not compatible with Xfinity stream listing error TVAPP-00116. I've had issues with Xfinity before, so started using the user agent. I was using Vivaldi 3.7 yesterday with the user agent still set at Chrome 77. I updated to Vivaldi 4 which says: [Chromium] Upgraded to 91.0.4472.79, and at first was able to stream, but soon still got the error message, which among other things says: "Supported Browsers
Chrome 89+, Firefox 89+, Microsoft Edge 90+, Safari 12+" Just to be sure it wasn't something else, I opened Xfinity in my Edge browser and it streamed fine, so I opened up the user agent window in Vivaldi, and it doesn't allow me to choose anything higher than
"Chrome 85.0.4183.83 Windows 10" However, Vivaldi 4 says it is upgraded to Chromium 91. I am assuming that if I could choose a Chrome 89+ setting in the user agent, that would make Xfinity happy. Can I do something else or does the user agent need to be updated still?

Hi - there is no such window. Are you using an extension for this?

So, I turned off the user agent extension and voila! Doah....
