I have a visionOS app using Apple's WebView and WebPage to display web content. When viewing a live YouTube stream last night, YouTube put up the warning in the area that would have the chat window:
Oh no!
It looks like you're using an older version of your browser. Please update it to use live chat.
Anyone know if YouTube is generating this from the server based on the WebPage's user agent string, from Javascript running in the browser engine, or something else?
Anyone know if and how it is possible to resolve this?
