    How to prevent multiple submissions?

    Asked by JenGetsShitDone on February 02, 2017 at 09:21 PM

    A form was submitted to me about a week ago. Today the exact same form came through, but the client that sent it the first time didn't submit it. It's like it filled in (all the exact same info) and submitted itself. Is this something I should be concerned about?

    It seems browser cache issue. When submitters don't clear their browser caches, it may cause this kind of submission issue. 

    If you don't want to receive multiple submissions, you can activate Unique Submission feature.

    Please have a look at the following guide: How-to-Set-Unique-Submissions-on-a-Form 

    If you need any other details, please feel free to let us know.

    Thank you.
