Yes, you can pause or end a quiz/survey. Once logged in, go to the quiz you want to pause, then click the “Deliver”. There you can edit the quiz/survey start/end time. If you set an end date which already passed, let’s say 8/22/2021, the quiz/survey questions won’t be shown anymore. Instead, visitors to your page will see the screen “Thanks for stopping by. We’re sorry, but this is now closed."
