Hi, I was experimenting this problem too (I have a MacBook Air M1 with Monterrey). Something i have noticed is that pinch to zoom fails when I am using the Preview app. I don't have problems with other apps, have you noticed it? Maybe, the problem is this app.I switched from a 2015 pro where touchpad was always for me perfect, here on the new 14 inch it feels weird. Kind of a step back comparing to what I had before. At times touchpad doesn't seem to register that I am trying to do "pinch to zoom". It's almost like I have to put my fingers in a specific ways for it to catch it. Kind of like regular "windows" laptops ?
Anyone else has noticed something like this?
