IS their a time limit on completing the form once someone has started to complete it? Is their an auto save whilst someone is completing the form?

Hello,

There is no time limit in completing forms. If you wish for your form to have an autosave feature, you can enable your form's autofill settings. This allows your form users to save and get back to the form later on with the fields filled up, so long as they are using the same browser.

You can check this guide for more information on how to enable this feature: https://www.jotform.com/help/227-How-to-Enable-Auto-Fill-on-Forms

Thanks.
