title_body: How to reset connection between drone and RC for MAVIC Air 2
upvoted_answer: According to page 36 of the DJI Mavic Air 2 manual the aircraft should be linked to the remote controller on arrival. 
  
  If not, you should follow these steps:
  
  
    
    Power on the remote controller and the aircraft.
    Launch DJI Fly. 
    In camera view, tap (three dots)  and select Control and Connect to Aircraft. 
    Press and hold the power button of the aircraft for more than four seconds. The aircraft beeps once indicating it is ready to link. The aircraft beeps twice indicating linking is successful. The battery level LEDs of the remote controller will glow solid.
    
  
  
  I think the issue was you didn't try to link it through the DJI Fly app.
