I have M705, Logi Options+ doesn't find my mouse, Logitech Options tells me to install Setpoint, Setpoint has been discontinued and G Hub does absolutely nothing. And if it did, i'm not interested in 'changing cool lights' but changing the setting on my mouse.
Are you really serious in that you're killing software that was working previously to force people to buy newer mouses? I mean seriously? Because if that's the future company policy, i'm happy to start looking for alternatives after some 20+ years of loving and using Logitech.
