Bug in stylus support...

I love this app and purchased pro version. Unfortunately there is a bug in pressure sensitivity function for stylus (it seems to remember the pressure value from the last stroke???), and it stops me from using it daily. I have Adonit Pixel, and often times a stroke starts with max. thickness even when I put the stylus very gently. It fixes itself quickly, but the bug makes things difficult. I dont see such behavior in other apps, so its not the stylus hardware.
