pressure option missing - animate cc

Hi there.

I was trying out Animate for an animation project and I found out that the pressure option for the brush is missing. I tried to start drawing first and then look for it on the toolbar, but nothing changes. It just isn't there. 

I'm using a 2 in 1 Dell precision 5530 with its pen (the pen supports pressure and rotation and has no problem on photoshop or illustrator).

Does anyone know what I'm doing wrong?
