Why session link does not pull up existing data

If I understand this feature correctly, we should be able to access any form by appending an arbitrary session string to the url:

https://form.jotformeu.com/71235149364355?session=AnySessionString

Then when this form has been submitted, we should be able to access the form and pull up previously entered data just by appending the same session value to the url:

https://form.jotformeu.com/71235149364355?session=AnySessionString

...but this is not working on our forms. It doesn't pull up existing data.

The session link is active until it is submitted.

Once the session entry is submitted, the session will be cleared and submitted data will be accessible from submissions page.

If you need any further assistance, please let us know.

Wouldn't it make sense to store this session id with the records, so that we can actually pull up the records using this session id instead of a generated submission id? This would certainly make it a lot easier to pull up existing submissions and let the end user continue the form later.

For how long would this session id hold on to the data for the user to finish the form?

Once the session is submitted it is considered as final. Submitted session cannot be accessed, but submitted entry can be updated with an edit link.

The session will expire if not submitted within 3 months from creation.
