I took everything apart, so it was just as received.  Charged everything full. reassembled and went through procedure again.Pairing was a success.

I will see what the morning brings.

p.s.  Mini 2 drone

Hi buehlerbg, may I double confirm if the controller is now able to connect with the drone? If they are not connected, please check the tutorial and try to relink the drone.
If the issue persists, please help to confirm if it is the connection issue between the controller and mobile device, a screenshot of the app would be appreciated.

Had success last night.  I will see what happens latter today.  I was able to update the firmware.
