I’m seeing the same issue, and this is a serious regression. Multi-touch simulation is not an optional convenience for apps with map, 3D, CAD, canvas, or camera-style interactions—it is fundamental to development and debugging. Requiring a physical device just to test two-finger pan, pitch, rotation, or two-finger tap dramatically slows down iteration and makes Device Hub unsuitable for these workflows. The previous Option-key gesture simulation was simple and effective.
