I can't believe Google/Chrome has this known issue since 2015 and earlier. Bottom line, they just want everyone to accept their new HTML links to a document using their Chrome PDF viewer. "Once you open the HTML link it is the PDF document you are seeing..." Such a crock because if you try to "upload" their HTML link you get an error message (because it is NOT the PDF document.) So I can see my PDF's but I can't upload them to other service providers (like dropbox, or PostImage.org etc)
