I set the Unique Question field to email id in one of my forms.

I set the Unique Question field to email id in one of my forms. It is working for the new entries but not working with old entries that were already entered in the google sheet. I tried to remove the integration and set new integration as well. Nothing seems to work. Any help is appreciated.

Hi, thank you for contacting JotForm support.

Please note that the unique submission only works on your form submissions and it does not check for any unique submissions on the integrated Google Sheet.

Since there were already entries on the integrated Sheet, unfortunately, the unique submission doesn't work on the data already entered on the integrated sheet.

I hope this information helps. Let us know if you have further questions.
