twitchy, sensitive, finicky

I gotta say the mouse is not great since I moved to a Macbookpro M1. There's aren't specific big glitches or crashes to point to, but the everyday experience is worse - I can't use it at all in googlecalendar - i can rest my finger on the scroll wheel and the calendar, just by the natural rhythm of my body like breathing, can shift months or even years (scroll wheel moves in microscopic amounts with massive consequence) Side scrolling is twitchy as ****. Especially in Preview (reading PDFs). I can no longer use the freewheel (that i got the mouse for in the first place because I don't like notchy scrolling) because it's too sensitive. But at the same time it's not scrolling super fast when I intend to scroll - so turning down the speed would just make it feel too slow. If I had to describe it I would say its like it's under-slept but over-caffeinated. Which is unfortunate because it was perfect before - when using on my older MBP.

Hopefully you can patch this or maybe there's a setting/tweak that you can recommend that can help. Thanks!
