Does the Virtual Stick cause the mission to stop?

Thank you for your thorough posting of what you are using. We wish everyone would do that... It skips a lot of back and forth. 

Yes, with Virtual Stick controls any stick input will cancel out of the mission. On waypoint controlled flights the sticks can be used to adjust yaw and speed in some cases. 

Stopping the programmed Virtual Stick flight is just how DJI has it. When it occurs it should drop a blue dot that any subsequent missions will come back to to resume the mission. There is no way to reset without landing first in Map Pilot Pro.
