"Send Cal" button not responding

[MegaMax5000]

While the Send Cal button is enabling after a certain amount of calibration, pressing the button does not seem to be making the 'green checkmark' appear in the status circle. I've tried pressing it many many times.

I'm on Windows 10, using an LSM6DS3TR-C + LIS3MDL with an arduino uno. I'm super new to this stuff and mostly following tutorials to get up and running.
