That bluetooth lag was annoying me on my first day, but since then I haven't noticed it: either it was fixed or I got used to it. The cursor is quite responsive for me.

Maybe you should try install "Logitech Options", because I did that immediately on the first day, which might have fixed it.

I have noticed bluetooth lag apparent with first party keyboard, mouse, trackpad on an M1 Mini.

But that was also happening in different ways on my non-M1 MBP.
