Hello, I had big problems with the PDF reader component under Android (under IOS I managed to use Web Viewer instead and it works fine).
At the beginning I tried to load a filename dynamically by pressing different buttons, but I got problems.
So I tried the most simple thing, create a Screen with a PDF_Reader component, put a file in the “File” field and open that Screen. Even in this very basic example I got the same error.
Finally I tried to put a valid URL instead of a file, but even this time it didn’t work.
Attached the error that I got in both Android 9.0 and 10.0
