Photoshop brush lag on my ipad air 3

Hi, this is my first time using photoshop on ipad and i thought it will be easier to get my work done but it seems photoshop has a problem with the brush feature. The line i draw only show up after stylus/finger is released (untouch) from the screen.

I didn't face such issue with another drawing app like autodesk sketchbook. Hope that photoshop team could respond and help me fix this problem
