Not sure when it started, but I can't fly in NFZ after getting clearance to fly when the controller is hooked up to my tablet.  When I connect my phone to the controller, I can take off.When connected to tablet, I use the phone as mobile hotspot to get wifi to the tablet.

Any ideas what went wrong?

I'm not sure what you want me to resign into.
I use Kittyhawk to unlock NFZ. I do that on the phone and download to the drone. I can then fly.Then hook up the tablet, and can't fly. I run Kittyhawk again from the tablet. It seems to go smoothly. but i can't take off.
On the DJI GO4 app, it tells me I'm in a NFZ and can't take off. If I attach my phone instead of the tablet, I can take off.
Hope this explains my problem a little better.

OK. A little unclear. DJI has their own NFZs in the software for the drone. Kittyhawk can give you clearance but DJI zones are not integrated into that. You need to do a custom unlock. Can you not use Kittyhawk on your tablet?

StarRider,  I think you have the same problem I do.  When you give the phone number to receive the verification code, it seems that you give your phone number of the one you mention in your statement of the problem, is that right?  Then when you go to fly, you try to use the Tablet with the controller, I think that's right.  All I can figure out at this point in time, is that the authorization rests with the phone, IT has the authorization , where the Tablet has not been communication with the authorization system.  I have had the exact problem and still do.  The only way I have found around it is to hook the phone that received the authorization directly to the Drone and copy/download it to the Drone, or do it with the Phone and Aircraft Controller.  Good luck, I sure hope this helps.

Have you tried unlocking here - https://www.dji.com/uk/flysafe/self-unlock

HH1, this is exactly my problem.  I'm thinking after getting authorization on the phone, downloading it to the drone, then swapping out the phone for the tablet the drone would be able to take off.  That is not the case.
There must be some way to accomplish this.

Yes, have also tried this.  Works when phone is attached, but not tablet.

I have Kittyhawk in the tablet also.  All seems to go smoothly with authorization, but when I try to take off it says I'm in NFZ and won't start.

You'll need a working data connection for the tablet to be able to update.

I get data to the tablet via wifi from my phones mobile hotspot.  Still no luck.

I have done as you described about getting authorization on the phone then downloading to aircraft, then switch to the tablet, and it worked.  However, I forget if I got the authorization while the phone was connected to the Aircraft Controller, or connecting the aircraft to the phone and downloading then.  After checking on Voice over Internet Protocol, and Voice over LTE, I have come to the conclusion that I can't get the authorization on the Tablet.  However, as others here have said the Mini 4 works well for flying the drone, so it is plenty good for areas where you do NOT need authorization.  I use it that way in the back yard.  Best of luck, I truly know what a headache you are going through.  Thanks for texting.  Also, does your tablet give the message:  "sorry that party has chosen not to receive messages."  When you try to text the tablet?  Another thing is that when the authorization is sent from Dji, it IS sent by TEXT.  I am with you the data part of the tablet and the wi-fi also do a good job, just won't receive TEXT messages or VOICE.

I use to be able to fly with tablet in areas I can't now.  Not sure which update this all started with. I'll contact DJI support to see what they come up with.
Thanks for trying to help me out guys.

Hi, thanks for the update. May we know if you could fly the drone with this particular tablet now?

StarRider, I went to the flying field today with both the phone and Mini 4,  I tried the phone first but once they coupled, the screen showed that I was in a NFZ and in the upper left it said that the craft could not take off.  I disconnected the phone and connected the Mini 4, that last night I used the APP "Kittyhawk" to get one of their FAA clearances.  Once the Mini 4 coupled with the Remote Controller and Drone, it showed that I was in a NFZ, but then a little window popped up with three check off things in it, saying something to the effect of getting an Unlock authorization.  Note:  The Mini 4 was using Wi-Fi and GPS only at the time, as far as I could tell.  I DID get the unlock and had a happy time flying.  So, I would say keep trying different things.  GOOD LUCK.
