Using photoshop on my macbook pro 16 inch M1. At frequent and random times, it disabled zooming in via trackpad pinching when Photoshop is open and being used. This disables the pinch to zoom across every app open on the Mac. The bandaid fix right now, is to open system preferences, and go to trackpad and switch the pinch to zoom setting off and on again, which restores the function. But this is not ideal - it always disables it again after some time, so you have to go back into system preferences and fix it again.
