How to prevent the user to scroll verticaly?

Thank you so much @natserrano for this code! It works perfect everywhere…

…except for the iOS PWA version I built per the excellent PWA tutorial that @JohnGiaccotto created here. The PWA Android scroll is disabled, its just the PWA iOS where the scroll has not been disabled.

@natserrano or @JohnGiaccotto do you have any suggestions for how to disable vertical scroll in an iOS PWA?

Thank you in advance for any help
