I have created a form that requires applicants to upload various documents in .pdf, .xls, .doc, png, .jpg. I also have Save and Continue enabled. When an applicant uploads a pdf or doc and clicks save and continue and then comes back to the form from their link, the docs, pdfs etc are not saved. Only the .jpgs are saved.
If they go through the entire form and submit, then all the documents uploaded are saved and forwarded via email.
