"The ABBS feature activates as soon as a user starts the survey by clicking the start button, generating and assigning a unique response ID. When you preview the survey, it is treated as a test response, and a response ID is generated for it as well. Once the survey is submitted, cookies are saved in the browser, which is why the preview link does not allow further testing.
As a workaround, you can either disable the ABBS feature temporarily or test the survey in incognito mode, where cookies are not saved."
