What is the Allow Duplicate Responses option?
The Allow Duplicate Responses option lets you decide whether the same respondent can respond to the survey multiple times for each collection group you create. Configure this option appropriately based on the purpose of your survey.
How to Set Up Duplicate Response Allowance
You can enable or disable the Allow Duplicate Responses option in the advanced settings of the collection group. The default setting is disabled, meaning the same respondent can only respond once. If enabled, the same respondent can submit multiple responses.
