Using "Save and Continue Later" with "URL Parameters"

When I use a custom link to allow users to save their form responses and return later, the following syntax works:

https://www.jotform.com/63415196670156?session=3884766714504882466Avengers

When I use URL parameters, the correct information is prepopulated:

https://www.jotform.com/63415196670156?session=3884766714504882466Avengers??contactPerson[first]=Tony&contactPerson[last]=Stark&fullLegal4=Marvel&nameOf=Avengers

But when I save the form and return to the form without parameters the fields are empty:

https://www.jotform.com/63415196670156?session=3884766714504882466Avengers

It appears that the system considers these to be two different forms. Is it possible to use both these features at the same time?

You have a typo error in your URL. The green part is ok. The red ?? should be a single &

https://www.jotform.com/63415196670156?session=3884766714504882466Avengers??contactPerson[first]=Tony&contactPerson[last]=Stark&fullLegal4=Marvel&nameOf=Avengers

Prepopulate your form with a new session variable "Avengers4":

https://www.jotform.com/63415196670156?session=3884766714504882466Avengers4&contactPerson[first]=Tony&contactPerson[last]=Stark&fullLegal4=Marvel&nameOf=Avengers

Save your progress by pressing next. Then reload the page with the new session:
