Unique Submissions: Ability to prevent duplicated submissions within a time frame.

I think I already found the answer below in the old replies (2013 - 2017) that this is not possible... or has it been added in the meantime? It would really be a big plus for Jotform if you would offer this feature.

Hello Ronald - Are you referring to unique submission?

Please note that the unique submission feature is already available: How-to-Set-Unique-Submissions-on-a-Form

Let us know if you are referring to something else.

Sorry for the confusion, I just saw your other post here: https://www.jotform.com/answers/2157071

Please note that we do not have a unique submission within 24 hours. If you want to allow them to submit the form again after 24 hours then you will need to delete their submissions so that they can submit the form again.

Check! Or I could probably set up a series of forms that are active for 24 hrs and plan these at 00:00 for several days in a row.

Still... a unique submission with a time limit would be a very nice feature (hint hint). ;-)

I will open a feature request for this, although we cannot provide an ETA or ensure this will be implemented, we will keep you updated via this thread. 

Thanks.
