3) Are you certain that the controller IS bound to the drone ?
Very certain because I have an air 2s and tried to link my controller to the mavic 3 and it would not stating it's bound to the other controller.
Reasons for those questions.
3) I ask because I experimented with binding my
mini 2 drones to my account, they DID NOT have care refresh. Whilst I was able to bind the drones to the chosen DJI account, I have several accounts, I COULD NOT bind any of the controllers to any of the drones, I could not and can not, find any place in the App to do that.
Once a drone was bound to my account I was able to use any of my DJI accounts to fly the drone and any of the controllers to fly the drone, including a spare controller.
I.e. the binding placed no restrictions on me or the drone at all.
I was greatly dissapointed with that and removed the binding.
From this experiment I presume there are at least two strengths of binding, one which does nothing and the other which can ultimately ground the drone.
1) & 2) If the drone and controller have the 'full strength' binding then, if you are not logged into the binding account I find it strange that you have not been at least warned that you are not using the 'correct' account and that the drone will be grounded after x flights unless you log into the 'correct' account.
This makes me wonder whether or not the drone has the weaker binding in which case I suspect that the controller is NOT bound to the drone.
You could perhaps post a screen capture of what the app shows concerning
a) the binding of the drone to a DJI account and
b) the binding of the controller to the drone.
If you do so perhaps those here with properly bound drones can comment on what they see.
Obviously mask or partially mask, serial numbers and email addresses.
If you used and are currently using the seller's account and that account was the account that set up the binding then surely you can use that login/account to undo the binding.
If it has been a while since you bought the drone and yet you have not been logged out of the App/account then it might be an idea to NOT update the App and equipment firmware.
Many people curse this automated "timed logout" and if it was introduced via updates you might have prior versions of the App and firmware.
Thought the drone need not be stolen, there are other explanations for the original owner's failure to respond, DJI could only ground the drone via an internet connection to the phone or controller, disable that connection and DJI can do nothing.
If you are using a phone i.e. you do not have a
smart controller, then you can log into the App ( needs an internet connection ) without the App being connected to the equipment and consequently the equipment does not 'see' an internet connection. It is possible that in those circumstances DJI would not pass on a 'grounding order' but note that is speculation.
