This must be the worst app ever made... makes me think twice before buying another logitech. Been using logitech mice for more than 15 years now and this software make me wanna throw it out of the window.
Buggy, keeps crashing, keeps disconnecting, keeps reseting you settings even though in app it shows the correct one, so u need to hard kill it(end process) and restart to work...
It's just horrible
