Hi There,

I just found HtmlWebViewSource cannot be updated when properties had been changed.
This works on Android but not in iOS, I think this is a bug of Xamarin.iOS.

Some code snippet here 
			<WebView Grid.ColumnSpan="2">
				<WebView.Source>
					<HtmlWebViewSource Html="{Binding HTMLSource, Mode=TwoWay}" />
				</WebView.Source>
			</WebView>

        public Command ChangeSourceCommand
        {
            get
            {
                return new Command(() => {
                    clickTime++;
                    HTMLSource = $"<html><body><p>Click time {clickTime}</p></body></html>";
                });
            }

        }

Thanks
