Can the person filling up the form return to where he left off?

I recently hosted a jotform on my website

https://inspections.thenavigatorsguide.com/training-for-seniors/

and I have received the following complaints:

The users start filling up the form, and move on to the next pages. if they stop filling up and leave, next time they have to start all over again.

The forms I have a quite long and are used for the preparation of a vessel. They make take several days to fill up and it is not expected that the users will fill them up at one go. How do I enable the users to return back to the place where they left off?

It is possible to achieve this using the Save and Continue Later feature that can be enabled in your form.
