PDF attachments are received as downloadable link

I'm also having an issue where my "Certificate of Completion" email, which used to include an actual email attachment with a certificate made using the custom JotForm PDF editor, is now only including a link to download the PDF instead. How can I get it to return to attaching the file itself rather than a link?

I did a submission test on your form and I was not able to replicate the issue.

Could you please disable the attachment, send a test mail, and then re-enable the option again?
Might be a temporary glitch.

Let us know.
