Jotform documentation issue

After uploading my requested documentation by the jotform owner, I clicked on the pdf link to view the letters in pdf form, and a new tab opens that says:

Whoops!

Unfortunately, the page you were looking for could not be found. It may be temporarily unavailable, moved or no longer exists. Please check your spelling and retry.

Please help!

I checked the form but could not find the submission in your link.

It looks like the form owner has already deleted your submission, hence the link no longer works.
