Do you know how many times a day I have to wait for minutes until the MX Master 3 and mx mechanical keyboard to sync the configurations with the PC even though the app works? do you know how often this affects my efficiency at work? Do you know how many times Logitech app plus was stuck at loading until I had to kill 5 processes for it to work again? I PAID HUNDREDS OF DOLLARDS FOR THESE DEVICES AND THEY OPERATE WORSE THAN A USB 10$ logitech/microsoft wired mouse. Can you please deal with these problems in a competent way?
