I have two MX Keys keyboards! I Love this keyboard - bought it as soon as I could get my hands on it. I use it with my 2017 MBP 13' TB with no problem via bluetooth.
It has aged really well too. Happy to see other MX Keys users out there.
When I type on the n, m , . / and the j keys, I feel like the front edge of the keyboard is bouncing on the table and the rubber in the middle front hits my desk to produce hitting sounds.
Could you please check if yours have this problem? Is it normal?

Hmm that's good to know. I haven't upgraded to Catalina yet but will hold off. Since I do not want to use my MX Keys with a dongle either.
This has been solved by installing the Logitech Control Center Daemon.
