I'm having problems with my MX Master 3 on macOS Monterey. I'm using Logi Options+ 0.61.2670.

The mouse works fine until I connect my bluetooth earphones (Galaxy Buds+) at which point the mouse starts lagging uncontrollably. This is mostly fixed by turning my MX Master off and on, which stops the uncontrollable lag, but even then whilst my earphones are connected the mouse still slightly lags.

I didn't have this problem on the previous version of macOS with the non-beta Logitech Options
