xamarin WKWebView, ipad does not support youtube full screen - xamarin

Question

I implemented a webview using the WkWebview renderer.
Fullscreen works fine on ipone. But it doesn't work on iPad.
An image like the one below will appear.
I saw an article saying to do webViewConfiguration.allowsInlineMediaPlayback = true and applied it but it didn't work. What's the problem?
Here is my code.
public class MyWebViewRenderer : WkWebViewRenderer, IWKScriptMessageHandler, IWKNavigationDelegate
{
WKUserContentController userController;
public MyWebViewRenderer() : this(new WKWebViewConfiguration())
{
}
public MyWebViewRenderer(WKWebViewConfiguration config) : base(config)
{
userController = config.UserContentController;
var script = new WKUserScript(new NSString(_JavascriptFunction_CSharpOpenWeb), WKUserScriptInjectionTime.AtDocumentEnd, false);
userController.AddUserScript(script);
userController.AddScriptMessageHandler(this, "invokeAction_CSharpOpenWeb");
}
protected async override void OnElementChanged(VisualElementChangedEventArgs e)
{
base.OnElementChanged(e);
if (e.OldElement != null)
{
userController.RemoveAllUserScripts();
userController.RemoveScriptMessageHandler("invokeAction_CSharpOpenWeb");
MyWebView myWebView = e.OldElement as MyWebView;
myWebView.Cleanup();
}
if (e.NewElement != null)
{
this.NavigationDelegate = new MyNavigationDelegate(this);
var webView = (MyWebView)Element;
webView.UriChanged += async (s1, e1) =>
{
NSUrl nsurl = new NSUrl(webView.Uri);
Configuration.AllowsInlineMediaPlayback = true;
NSMutableUrlRequest request = new NSMutableUrlRequest(nsurl);
await SetCookies();
LoadRequest(request);
};
if (!string.IsNullOrEmpty(webView.Uri))
{
NSUrl nsurl = new NSUrl(webView.Uri);
NSMutableUrlRequest request = new NSMutableUrlRequest(nsurl);
await SetCookies();
LoadRequest(request);
}
}
}
}
Can you tell me what I did wrong?

Configuration.AllowsInlineMediaPlayback = true; is the OPPOSITE of what you want.
Set it to false:
Configuration.AllowsInlineMediaPlayback = false;
If that doesn't fix it, then you may need to do that earlier in the code.
See if it works when done in the constructors:
public MyWebViewRenderer() : this(new WKWebViewConfiguration())
{
EnsureFullScreen();
...
}
public MyWebViewRenderer(WKWebViewConfiguration config) : base(config)
{
EnsureFullScreen();
...
}
private void EnsureFullScreen()
{
if (Control.Configuration.AllowsInlineMediaPlayback)
Configuration.AllowsInlineMediaPlayback = false;
}
