Partial completion

Hello everybody, 

i invited a tester to see if this fonctionnality promised by typeforms would work and it failed. Do you have an idea what s at stake ? 

“Respondents can start your typeform, close it, and return later without losing their answers.

Your audience doesn't have to complete a typeform in one sitting. They can start to fill one in, close it, and then return later and their answers will still be there. The only rule is they have to be on the same browser and device (and not in Incognito or Private browsing mode). Their answers will be kept safely in their browser's local storage, for 15 days.”
