DJI ask me to video the controller making the nose. Then they said something in the controller was bad and that I would have to send it in for repair. I did as requested and then waited. Ten days later I received an email that informed me that testing was completed and there would be no charge for the repair. I called back a few days later for an update. This time I'm told that nothing was wrong with my controller but in fact my Pro + was not compatible with their simulator. Long story short, it took the techs weeks to determine that heir own simulator does not support their best controller.
