I have followed the getting started code here: https://help.syncfusion.com/xamarin/sfpdfviewer/getting-started

The only change I made was that instead of loading a pdf doc from the project itself I made it load a random PDF document from the web 

protected override void OnAppearing()
            //Load the PDF
            byte[] pdfData = null;
            using (var wc = new WebClient())
                pdfData = wc.DownloadData(new Uri("http://www.pdf995.com/samples/pdf.pdf"));

            pdfViewerControl.LoadDocument(new MemoryStream(pdfData));

Intermittently the viewer becomes unresponsive and I cant interact with it like scrolling or zooming
