Document will not attach to auto reply

Document will not attach to auto reply. I have tried several times for a particular form, sometimes it has attached but when I removed all of the info that is submitted on the form at South somehow the document does not show up in the auto reply.

What is the total size of the file attached in your autoresponder? If the total size of the attachment is more than 5MB then the submission’s emails will be sent without attachments.

If the file is less than 5MB, could you please let us know if we can send a test submission to this form to test it from our end: https://form.jotform.com/91004745442956?
