Apologies
By under I just meant switch the place of the call here
So change the code to be
UpdateUserAgent
webViewHandler.SyncPlatformCookies(platformWebView.CoreWebView2.Source).FireAndForget();vs
webViewHandler.SyncPlatformCookies(platformWebView.CoreWebView2.Source).FireAndForget();
UpdateUserAgent

I don't think the source will be set to the right value at this point
For the UItest can you add a part that validates the cookie was set?
like maybe after navigated has fired you can read from the cookies to see if the cookie you added is present?

We've added cookie validation to the UI test as per your suggestion. Could you please verify once?
