I have some users who reported what can be shown in the video - on iPhone.
They can place one or two fingers on the screen and then accidentally scroll outside the page layout which makes the shop difficult to navigate.
I hope someone can help me ‘lock’ this issue out to avoid difficulties and weird swipes.
I am using the newest Dawn theme - https://puretime.dk

@PureTime Thanks for posting here. I have checked on iPhone. Chrome and Safari browsers, but im not seeing this issue there.
I’ve tested on more users, all have this issue. One or two fingers on the screen and you can move the page around by moving your fingers.
Iphone only
Hey @PureTime,
Thanks for posting this Question to Shopify community.
The issue that you facing is pretty common on iphones but it’s fixable.
To fix this issue you need to follow these steps:
Go to Shopify Admin >> Online Store >> Edit Code >> base.css
In the end of base.css paste the following code.
@media only screen and (max-width: 767px) {
body {
overflow-x: hidden !important;
}
html,
body {
max-width: 100% !important;
position: relative;
overscroll-behavior-x: none;
-webkit-overflow-scrolling: touch;
}
body {
touch-action: pan-y;
}
}
Once you paste this code your issue will resolved. Please let me know if you need more help.
And if the issue is resolved then don’t forget to like it and mark as solution so that other Merchants can find this topic.
I am happy that it’s fixed now.

Hi. I found out it actually just caused another issue 
I need to allow the user to still use the zoom on the screen (for bigger texts, zooming into images etc) - and this CSS kills this option.
Do you have a fix that works on the accidental behaviour mentioned in the first post - that would still allow the user to zoom?
