Touch backend not working

Hi -

The documentation does not address this but is the touch backend supposed to simply add touch based dragging or it excludes the regular dragging (in which case is there an all in one backend?..)? I ask because I had setup a basic card for dragging which was working fine on the HTML5 Backend but when I switched to the TouchBackend it stopped working.

  const [{isDragging}, drag, preview] = useDrag({
    item: {
      type: ItemTypes.CARD,
    },
    collect: monitor => ({
      isDragging: !!monitor.isDragging(),
    })
  })

// structure of how I laid out the draggable component.
<div ref={preview}>
  <div ref={drag}>
  // some svg icon as handler
  </div>
</div>

Any help is appreciated. Thanks.

I have the same issue - preview not showing up while using TouchBackend

Ah that seems to have done it! Although now the preview when I drag is not working. Is

        collect: (monitor) => ({
            isDragging: monitor.isDragging(),            
        }),

Not supported or called something else?
