So, a while ago I had an issue with orbit controls where the touch events were conflicting, and I found the solution somewhere which told me to go into OrbitControls.js and comment out the function event.preventDefault(); under the onTouchStart function. That resolved that particular issue.
Now, I am having a similar problem with Drag Controls. My code works fine on the laptop, but when I run it on mobile, again the touch events seem to be conflicting. So I tried to do the same thing. In DragControls.js, under the onDocumentTouchStart function, I comment out the event.preventDefault(); however this time the problem was not resolved.
Was wondering if anyone else ran into this issue and has a solution for it.
