Based on my recent experience when the quiz was suddenly disrupted (I emphasize that the quiz was conducted from the mobile app and answered by mobile devices) due to some glitch, it would help as a Plan B if we could launch a quiz directly from some question other than just first question. Albeit the Slido staff was telling me I could just keep pressing the "stop and next" button from question to question, it is very clumsy in case of multiple questions, as it is typically expected to be contained in a quiz.
So, as a Plan B, there could eventually be an option (button or a menu item) that could enable us to jump on a certain question and continue the quiz from there. Alternatively, if the staff would check it within a code up to what question the quiz was successfully executed (with participant answers) before the disruption, it could automatically offer us to resume the quiz from the question that should follow before the quiz was disrupted (letting the admin adjust it manually to +/- 1).
