Hi,

We are experiencing a similar issue related to the SfRichTextEditor on Android. In fact, we are facing the following exception:

System.NotSupportedException: 'Unable to activate instance of type Syncfusion.XForms.Android.RichTextEditor.WebViewExt from native handle 0x7feac48268 (key_handle 0x7c1a184).'

Remarkably, this exception in our case only seems to be thrown when navigating to a content page with a rich text editor and immediately performing a back navigation even before the control is finally rendered. 

Best regards,

Florian
