Hi Team,I’m experiencing a significant delay when submitting a survey.When the send confirmation email option is enabled in participant settings, it takes around 2 minutes for the survey submission to complete after the participant clicks the submit button.If the confirmation email is disabled, the survey submission appears to complete normally without this delay.

Any suggestions on how to troubleshoot or resolve this would be appreciated.

Thanks,
