Prevent duplicate submission at the start of the flow

I have a use-case where I will be passing a hidden field and would like to block the user on the first page of the form and take them to a different thank you page and prevent them from filling the entire form and showing a blocking message.

Hi TNKH, Thanks for posting this feedback request. You can reach out to us directly via our support channel here: https://tally.so/support Regarding our Prevent duplicate submissions feature, it is designed to detect and trigger the block after the respondents click the final submit button. However, I can see an improvement for the IP address flagging in the beginning indeed, so I'll add you to this request: https://tally.so/feedback/board/p/preventing-duplicate-answe….

Hello Sathvik, Thanks for sharing this feature request — we completely understand your use case. At the moment, the Prevent Duplicate Submission feature runs at the end of the form (on submission), so it’s not possible to block users at the start of the flow based on that check. We’ve noted your suggestion and will take it into account for future improvements.
