I have the Surface Pro 3 and it doesn’t work. I’ve installed the recommended Win Tab driver but the pen only draws for a few seconds and then stops working again. I’m not sure if my Cintiq drivers(I use my Cintiq with my Surface Pro) might be the reason.
I meant that drawing directly on my Surface Pro with the Surface pen doesn’t work when using Animation Paper. My Surface pen works just fine with Sketchbook, Photoshop, TV Paint, Toon Boom Animate etc but not with Animation Paper.
