Hi! (Newbie question) I got LEGO Mindstorms 51515 for Xmas a few days ago and I love it! Straight out of the box, the Mindstorms App prompts you to calibrate the motors (or rather it calls it "updating" the motors). For one of the four motors, I didn't do such a great job and the zero position is a little bit off. I would like to recalibrate it, but after much searching, I just can't locate the option on the Mindstorms app. Can anyone please help me figure out how to trigger the motor calibration sequence again from the Mindstorms App after the initial installation? Thanks!
