I'm facing with a very weird issue with a Xamarin Forms application on IoS after the latest OS update. Basically this application uses a WebView renderer to navigate a company's intranet portal which has NTLM authentication. I implemented the web renderer to handle the authentication process and it was working fine till few week ago but after Apple's last update the webview has stopped working.
Unfortunately there is no error code, exception or explicit message from the SDK, and the authentication process is working (I can see it from the logs), by the way the webview's content is all blank.
I have tried to navigate to other websites (with no authentication) too (bing.com, google.com, xamarin.com) but the issue was still there.
Anyone has some suggestion or hint?
