Absolutely horrible, inexcusable support for the MX Master 3, which should be the top of the productivity line. 50% of the times I try to use the mouse, all the configurations are gone. Recently there is even worse behaviour, since it randomly reverses scroll direction (even after I toggled off natural scroll) and it jumps whole screens when scrolling instead of the regular three lines. I used a Performance Mouse MX for over 8 years, and now I cannot in good faith recommend a Logitech mouse ever again. I'll be selling this mouse and buying from a different brand in the future.
