I seemingly can only fly a few hundred feet in any direction no matter if I am at a park or the beach. My other DJI Mini 3 has no problem.

My goggles on the FPV say a phone number is not registered.

I did buy it used.

I don't know how to fix that. That may be the fix.

Hi there. Thank you for reaching out and we're sorry for the trouble. Please update the firmware of all the components via DJI Assistant 2 software. At the same time, update the DJI Fly app on your mobile device then connect to the unit, and check if the issue persists. You may download the DJI Assistant 2 software using the link below also I will post a tutorial on how to connect the unit with the app. Please keep us posted. Thank you.
