==================
We would like participants to be able to update their responses after completing the survey using the link provided in the invitation email.

The following settings have been configured:
Global survey settings
->Participant settings
->->Anonymized responses:OFF
->->Enable participant-based response persistence:ON
->->Allow multiple responses or update responses with one access code:ON

However, even after participants resubmit their answers, the responses remain as the initial submission.

What else do we need to configure?

Thanks a lot in advance.
