Step sensitivity? Any way to change?

I just picked up a new Mi Band 9, and it hardly ever tracks steps except if i flail my arms wildly.

Is there any way to increase the step sensitivity? When i walk on a treadmill, it hardly ever picks up steps. I'd rather try to fix this one versus just buying something else since i've been happy with Mi overall in the past, but im at my wits end trying to use it as a basic activity tracker. Thanks!
