i exported my game as a single file html, to send it via whatsapp, it works fine on every android i tested, it also works fine on older Iphones (6 and below) but cant be opened on newer iphones (on the safari), i presume it is some kind of security restriction preventing a non-web .html file to be opened but i couldn`t find it to set it off.
I presume maybe Chrome can open it as it does on android. but whatsapp always open .html files with safari on iphones
