Android/iOS not scrolling back to the top

Hi, I've created a Quiz form with several sections. The quiz is supposed to be answered on a mobile phone since I am printing a poster with a QR code (btw, nice addition!). On Androind and iOS, the next section/page - after pressing "Next" - doesn't automatically scroll back to the top, staying either at the bottom of the page or at the same "scroll level" from the previous page.

I only tested on Chrome for mobile in both Android and iOS devices. I've attached a video recording showing the issue from my Android device.
