I tested on an iPhone. I sent in a submission then closed the safari browser. when i re oped the browser hours later it sent a duplicate submission. Is there any way to block duplicate submissions by default in a form?

This issue happens on mobile devices only as the page is reloaded and re-submits the data. You can set up unique submissions, so your users receive an alert when re-submitting the form. These guides will help you with this:

Another option is to replace the Thank-You page with a URL, if you do not have a custom link, you may use this one: https://www.jotform.com/thankyou.html
