I would like to inquire about a controller error that occurs when using the Rich Beta version on Mavic 3 Enterprise.

I created a mission and started it, but I can’t use the stick during the mission. Is it intentionally blocked from using the keys while the mission is in progress? If you stop the mission, you can use the keys right away. Please check if this is an error in the beta version.

This is a very confusing and unclear inquiry.

What is the “Rich Beta version” ?
What controller ?
What “Stick” ?
What “Keys” ?

There are 4 types of Heading Modes.
There are 3 types of Gimbal Pitch Modes.
