Hello there - I just wanted to share that my MX Master 3 does not work on. my Mac at startup - I cannot use it to go between user accounts etc. And on a number of occasions I've been 'locked out' of my Mac - to solve this, I need to use the Apple Magic Mouse - which I thankfully kept. Only after I've logged in does the Mac realise I have my MX Master 3 - and connects to it. I have an M1 iMac 24" - and it would be good if there was a solution to this issue.
