Can the same form be filled out by the same person multiple times without erasing their data?

I tried the steps above and it worked well but I am stilling having an issue. My main question is:

Can the same form be filled out by the same person multiple times without erasing their data?

Sample Scenario: Tanya fills out the "First Form" (to get the session ID) and then clicks on my form "Main Form" (the type of form I created is a planning form - the save features helps my clients to save and continue their input later before submitting). Tanya completes 3 out of 5 pages but decides to save and continue later. She gets the link to where she left off at through her email. In the meanwhile, Tanya then decides to fill out the same form with new information because she has a new event to plan (she repeats the steps as she did the first time and saves the form).

When Tanya goes back to the first form, the information from the second form is there instead, so all the information she had put in the first form is gone.

Added Question: Is there a way to create separate sessions so this form can be filled out separately with new data and not connected? Or that there is a unique URL all the time? or is it a URL problem? I used this format to try to make the URL link unique: ?session={unitID}{name} but it is still doing the same thing (erasing the previous information).

The purpose of my clients saving their info is so that they could go back to that their form without any detail they put being erased regardless if they filled out the same form with new information.

Thanks

Please note that we have deprecated the user guide shared above and instead we have merged that with the auto fill settings in the Form Settings as shown here: https://www.jotform.com/help/227-How-to-Enable-Auto-Fill-on-Forms 

When you enable that, the form shows a Save button. Upon initially clicking the Save button, the user gets a saved form session link, which they can fill any time later and also multiple times. Just they have to ensure that they click the Save button on the form.

However, using the earlier option, when user fills the data, revert and fills again at a later date, the already entered data will remain in the form. The session link is created on the second form. So when the user fills the form at a later date, they will be taken to the second form and not the first main form. But, please ensure that the session link does have an expiry of 90 days after which all saved data will be deleted. 

Please try the above Save method for your "added question query" and let us know if it works out as expected.

Thanks! It worked

Each session link shall be having a unique session ID. If you are referring to the the original question on the form, Please note that when the form data is saved using session link, the data on the form will not be displayed after submitting the form. The data can be only displayed on the form after submitting the form by using 'Allow Browser AutoComplete' option.

Thanks!
