You may create a link for the file using the following link: https://cloud.acrobat.com/send
(i) Click Add Files > Choose Files from My Computer
(ii) Select the pdf file and click "Create Link"
I resolved the issue by clicking the option to save the files "Best for
electronic distribution" when saving them as PDF. This solved the problem.
