I had prepared a quiz and had put in 30 sec response time on all slides. Made some final adjustments after a test and changed the number of response options. I think that even in some cases I just changed the text of the question. The system then changed the response time to 15 sec - without any information appearing. I first discovered it during the quiz and the participants were upset that they didn't have time to answer.

Ideally, I would just like nothing to happen automatically, alternatively be asked “do you want to change the response time”.

I would also like that when I start from scratch and build a quiz, that I should be able to put certain things (like the response time) into all the slides in this presentation, so I don't have to make the change in every single slide.
