Hey guys! I recently purchased a used Mavic Air 1. And I'm having trouble using the DJI GO 4 app on my drone, when activating it it returns the following error to me: The device being connected to is not the one being activated. Please connect to a genuine DJI device.  This way, I can't use the DJI app on my drone, I was only able to fly with third-party apps.  What does this error mean? And what should I do to fix it?

Hi, Luis. Thank you for reaching out. May we ask where did you buy the drone and can you please provide us the Serial Number for us to check? Please refer to the video below to activate the Mavic Air:
