R.e. ScrollView behaviour in Worldspace UI on Mobile devices:

 
On touch devices, the scrolling should work as follow: * When we touch the scroll bar and move it up and down, it should follow your finger. And the grid should move in the opposite direction. That works as expected in the video  

• But when you touch the grid and drag it around, the grid should follow your finger, and the scroll bar should move in the opposite direction. That's not how it's working in the video

This could potentially be a new property that would invert current behaviour.
