link to a pdf file shows invalid format.

Hi speedijim, thanks for checking in with us - I'd be more than happy to help!

As a first step, could you send me a screenshot (without any personal info) of the exact error message that you're seeing? 

Thanks!

How do i send that screen shot

Take a screenshot on your device showing the error. You can then use the Photos icon in the Reply window to add the image to your reply here.

That being said, I can open that link on my phone without an issue.

Thanks for the screenshot, speedijim. 

Could it be that you don't have the relevant app to preview the .pdf file? 

Could you also copy-pasting the link to your mobile's browser, but replace the "1" with a "0" to preview it instead of downloading it? 

Let me know how it goes!

I open many pdf files on my android phone. I have tried the link with a "0" and a "1". Neither works. That is why I am seeking help here... Jim

Ms edge did open the pdf.... But individuals that access this file will only have Chrome installed...
Thanks

Thanks for trying that out for me, speedijim. 

Could you send me a screenshot (without any personal info) of what you see when you copy the link, replace dl=0, and paste it to your primary browser to preview it?

Have you also tried previewing other shared link of a .pdf file by any chance?

Keep me posted!

I copied the link and pasted it into Chrome. It worked but first asked me to install Dropbox. Or go directly to the site. Going directly opened the pdf...
