I am sharing an anonymous View Link - no sign in required with external clients and instead of opening a PDF in the browser, it downloads the PDF and says save as instead. I can open the PDFs directly from the library and I can open other PDFs but not one sent using the view link or edit link.
I have checked the pdf add-in is enabled and other settings but I am now stumped. I would appreciate any responses that anyone can provide on this please? Thanks.
