The latest version of Options+ with my MX Keys wireless keyboard and M720 Triathlon wireless mouse is quick to stop providing my custom mouse button mappings, falling back to the defaults. The devices are being shared between three computers and I am frequently switching between them. All are using Logitech Unifying Receivers. I had to turn off Flow as well because it would suddenly fail to switch when moving to the edge of the screen. Options+ would register an "Error" and instruct me to turn the mouse off then back on.
