Mouse detection (MX Master 3S Mac) is still very slow! It takes 5-10 seconds for my iMac to pick up the mouse settings - which I have set to high sensitivity and fast movement. So the mouse feels very "dead", moving slowly and sluggishly for that period of time. And that period of time restarts every time my iMac screen goes dark i.e. my iMac goes into sleep mode. Please try and improve the Logi Options software to deal with this. The software also doesn't want to update the firmware on the mouse. It's not saying that there aren't any updates to apply, it's instead saying that it can't see the mouse at all - while the rest of the Logi software sees it no problem at all!
