I CAN'T DRAW CURVE LINES WITH MY DRAWING TABLET!!!

So i've just dowload my Adobe Animate CC but when i try to draw in it, i couldn't draw a fully curve line with my pen and tablet!
It's still normal when i draw in photoshop (in the video) but when i turn to Animate CC it just doesn't work!
- I've tried reinstall it, update the lastest verson of Animate CC but is it still doesn't work!
Here's the video :
