I created a site with 3 webpages, page1 is used to upload image file (the file could be in pdf, docx, jpeg or png).

After uploading, user will click button to generate a QR code for the file and navigate to another page (page2) for printing of the document.

The QR code will have a URL that redirects to page3 when scanned, so that the document that was uploaded and created QR code for will show or display.

But from my code, when the QR is scanned, it takes me to page3 but the document does not show.

Some document like PDF shows in laptop browser BUT NOT IN MOBILE PHONE BROWSER.

How can I make this work?
