I have found today that to get the Moverio to pair with the Mavic2 controller, drone, Go4 app that you have to follow a strict sequence.
Plugin the Moverio touchpad
Turn on touchpad
Turn on the drone
Turn on drone controller
Plugin Micro USB into the righthand side of the touchpad
Plugin USB into the rear side of the drone controller
Open the Go4 App
Works for me..... good luck
