Sure, i very tired with tap to click on trackpad problem since i bought pro M1 on june 2021.
First problem is: command + tap, or shift + tap, tap missed 3 times, it's mean you need action with command + tap, you need press command + tap tap tap (3times tap)
Spent 4 months with all the ways, i found and fixed the issue by hold down caps lock key by a stic, see image attached.
The second one issues when i upgrade to Monterey: sometimes, tap to click is not working effectly. I try to use beta version, the missed tap is same as on version 12.0.1, 12.1 beta 1, beta 2, it increase on 12.1 beta 3, it's make me felt so bad, angry and finally must back to Big Sure 11.6.1
