[Problem/Bug]: Webview2 is now detectable by security firewalls when data scraping #4444

What happened?

Hi, I have been using webview2 for years for web scraping without being detected but with the new 123.0.2420.53 version it is now detectable, I do not know if by headers or something different but I cannot use it anymore on the site I used to use for a long time. My app is still working fine with older versions. I mean everything is fine but firewalls are somehow understand it and block it. Could you please revert what you have done? At first look Accept-Encoding header comes with different parameters but I cannot change it because they can still block I think you have changed many things and now they can easliy understand it is not the Edge browser, previous versions did not have this issue and they cannot differ it from the Edge browser. Kind regards

Could you please provide more details what your app is doing? If you run SampleApp - do firewalls block it also?
