I CANNOT BELIEVE that Logitech Options PLUS DOES NOT uninstall the "OLD" Options software!! Now I understand why my MX Keys and Anywhere 2S are behaving weird, the programmed keys are not working most of the time. BIG no-no for Logitech. It should be an UPGRADE, as I was told before installing. Only several days later I discovered that I have both Options AND Options "plus" installed.
