    Hello! Any estimates when the fix will be available in release versions (not beta)? The latest version where S-Pen works is 2020.3.16.

    Hi! I've found another related bug with S-Pen: IBeginDragHandler, IDragHandler, IEndDragHandler don't work. It looks like Unity changes 'scrollDelta' instead of 'delta' when dragging with S-Pen.

    Would be great if it was fixed in 2020.3 as well
