Error - Failed to load pdf document

I have been trying to download a media attachment for one particular result in a project both through the “DATA” tab for the project and through link in the XLS download. I get this error - Failed to load pdf document. Is this a data entry issue (i.e., an issue on part of the person who entered the data and uploaded the pdf) or on my part as Account Admin or an issue on kobo?

Welcome back to the community, @AvaB! Maybe try downloading the media files to see if you can download them on your PC.

@AvaB, try using this approach as outlined in this post discussed previously:
