I have a scroll problem only on iOS in mobile version. Sometimes I get stuck on the top of my page if I scroll fast. If you test this page on iphone http://www.espace-piano.ch/ESPACE_PIANO_WEB/FR/cours.awp you will sometimes have the same problem as I have. The problem is often after the page refresh. If I switch to "computer version" on safari on my iphone, I no longer have a problem.

Is it possible in javascript to force the browser to "computer version".

I already have this code to know if the user is on iphone..., I just miss the code to force in "computer version" on the browser.

let isIOS = /iPad|iPhone|iPod/.test(navigator.platform) || (navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1);
