Yes, by scrolling i refere to the up/down component of a swiping motion on the screen, moving the whole image/page.
This part works fine.
The problem I’m having is that in order to get the line to move right or left, the swipe (at least for me) needs to be exactly horizontal.
If I swipe diagonally or in a circle, the page is moving up and down, but the line is not moving right or left.
