How to allow users to save the form and continue it on the date they want?

2. I've reviewed your documentation here about how to Save Forms and Continue Later. But I'm confused...in this example you're using the email INSTEAD OF the session ID?

The "Save and Continue later" and continue later feature uses email as the best way of uniquely identifying an account and uses the email to generate a Session ID that will uniquely identify to this account. So in a way the Session ID will be linked with the email address.

This is the reason we refer to email instead of Session ID.

Hope this answers your question. Kindly feel free to let us know if you need further assistance on the above.
