I am about at my wits end with these logitech devices. been using your wireless mice for almost two decades, but this master series is the worst. both the master 2 and 3 mice constanty forget their settings. every time I lock my desktop I have to relaunch options or otpions + to get it to re apply my settings. not to mention that I now need to run 3 different logitech apps on my computer to connect to my devices (setpoint, options, and options +) this is a consistant dialy problem. evedry **** day. at least add the mx master 2 to options + so I can drop the options app. The reason I use options plus is for the thumb scroll without it it is either way to sensative, or inadequately sensitive, there is no in between. options + at least fixed that issue.
