How to re-direct back to a specific question in the survey from external links like eye tracking, facial coding, etc

Hi There :wave:,

Welcome to the community, let me suggest a possible solution here, if the users are filling a unique link generated for them individually, then if they come back and click on the link, they can continue from where they left off.

Hope this helps.

Cheers
