I have submitted about this before and doing it again. I am requesting that you guys at logitech look into why the horizontal scroll works intermittently? I love the M3 Master Mac Mouse but the horizontal scroll is always giving me trouble from time to time. The products are amazing and worth the money but the horizontal scroll only working sometimes is a pain. I work super fast and use the mouse and keyboard for the customization to efficiently work quick but the horizontal scroll is the only thing this far that seems to slow me down.
