Hey, I'm Jaden, currently running the bigsur 11.5.2, and using a mx master 3. Right now, the scrolling wheel is not working properly, as the scrolling direction option in logi op + doesn't work. It is in the natural mode, no matter how i change it. This mouse has been great for me so far, but I hope this problem could be solved. I did talk to one of the online chat assistant in the logi website. They were completly useless, and had no clue on what they were saying or how to solve this problem.
