PDF Viewer not working on Android using version 19.1.0.57

When you try to view a PDF file in the PDF Viewer (SfPdfViewerServer) it doesn't show the PDF file when trying to view on an Android or iPhone device.  This can be reproduced using your Blazor demos at: 

https://blazor.syncfusion.com/demos/pdf-viewer/default-functionalities?theme=bootstrap4


The "PDF Viewer" example is not displaying the PDF on Android version 11 with One UI version 3.1 or on an iPhone.  You are able to view the PDF in a browser on a windows 10 computer.

In Feedback 19725 I reported the same error with a work around.  Now the work around does not work (nor would I want to do the work around I would have to do).

When I try to view your example (see above) using remote debugging from my Android phone, the following error appears:
