Can users revisit their form and save?

If someone is completing a long form are they able to save and come back to the form later? Also if they submit is there anyway for them to get back into their form and make changes? 

Yes, there is a method that will allow your users to start filling out a form, close it and go back and continue filling it out even in a different device, you need to get two forms, the first one where you will capture the basic data and where you will generate a session link to the main form, the one you need to get filled out. 

To get more details about this method, please check this guide: How-to-Save-Forms-and-Continue-Later

To allow them to edit the submission, take a look on this guide: How-to-Let-Users-Update-Their-Form-Submissions-at-a-Later-Date
