I have a hype file embedded on a page. There is a vertical drag element controlling the timeline. This works fine in desktop browsers and on Android devices. However, it seems recently it is not working on iOS when embedded. When you try and drag the element the page scrolls too, as if the two elements (the page and the drag element in the hype div) are conflicting. Any thoughts? This seems to be a recent thing in recent iOS update to safari. As it used to work fine.
