Can someone leave a form and go back to finish later?

Yes, you can enable the autofill feature on your form so that your users can leave a form and come back to finish it later. Here's how: How to Enable Auto Fill Feature. Please note that this method only saves the field values in the user's browser. They won't be able to continue if they view the form using a different device or browser.

If you want the user to be able to continue using any device, you can check out our Save Form and Continue Later feature here: How to Save Forms and Continue Later.

Please let us know if you need further assistance.
