center of gravity callibration

[dijkvaneenmaarten]

Hello,

In my tello app its impssoble to do a center of gravity callibration.
Is this normal?
The IMU callibration is blue and can be done but the center of gravity is grey and can not be done.

Threads say you should only do it when it prompts a message about it.

You can do it while hoovering.
