I was having the same issue as many on this forum but found a resolution that someone might find helpful.

We had recently transferred our website to WPEngine and after we did the plugin seemed to stop working.

After playing around with this for some time I noticed that if I uploaded a new PDF through the Media Library and DID NOT look at the File URL when I would go to replace that PDF and then look at the File URL it would be correct. However, if I did look at the File URL before replacing the PDF it would not update with the new PDF. That’s how I discovered it was a caching issue. However I was clearing browser cache, purging the cache through the WPEngine Dashboard, looking at the page in other browsers, using incognito mode, and it still wasn’t showing the correct PDF when previously looking at the File URL. I then looked at the URL on another device, one that had never been to that URL before and boom, the PDF shown was the correct one.

I found out that when we updated our DNS records when moving to WPEngine we used CloudFlare which has it’s own caching service. I purged the CloudFlare cache and that did it. Multiple levels of caching was the culprit. I disabled the caching on CloudFlare so I can hopefully avoid situations like this in the future.
