I've taken over the design of a survey in survey 123. I'm trying to add a question to the second page of the survey. It allows me to do that, and it confirms that the change is saved, but when I close and reopen the survey form the new question isn't there. It hasn't been published, we are still in the design stage. I must be missing something - can somebody help me out? I haven't used survey 123 at all and have a short deadline.
