I have a laptop with a touch screen (actually, it is a Surface tablet) and also an iPad. When I use OWA on my iPad, it is optimized for touch input. For instance, some buttons are larger and there is an options bar at the bottom.

However, on my Surface, it always loads the mouse optimized version. This is true even when I detach the keyboard and use the Internet Explorer Modern App instead of the Desktop version.

Is there any way to get my Surface to load the touch optimized version of OWA as well?
