Is there a way to allow a user to come back to a partially completed form (cookie / persistence)?

Answer:

There is a way to allow a user to come back to a partially completed form. For this, you need to enable the "Form submit as draft" feature in your form from the settings tab of your form.

This feature allows users to save incomplete forms as drafts. When the user saves a form as a draft, a system-generated draft link is created.

The user needs to copy this link and when they want to finish the form, they just need to paste the copied link into their browser to continue filling out the form from where they left off. If they need to change data in previous fields, they can do so and then complete the remaining form and save it.
