I upgraded to the latest gspro, LB2, and tx firmware and now the drone won’t arm to start a mission.

Tried it on two different drones and same thing happens. In the go app all is good and I can fly without issue in god mode.

In gspro I create the grid, click the blue airplane, mission is loaded no problem to the drone but the grey airplane to start flight does not turn blue such that you can take off.

No xcam is attached but we never have used or needed an xcam in the past

What did you change DJI?

I meant to say GPS  mode not god mode of course.
