What happens if someone is in the middle of a response when the survey is closed?

When a survey is closed, participants who are in the process of completing their response will not be able to continue their submission. The correct understanding is that progress is not saved past the closing of the survey. Therefore, once a survey is officially closed, any individual who is still actively participating will lose any progress made during that session.

It's important to note that participants typically have to submit their responses before the survey closes; otherwise, they will not be able to submit any answers at all. Options suggesting that they can finish later or that they receive a warning indicate a level of flexibility that does not exist once the survey is no longer accepting responses.
