I'm sure this was covered somewhere before, but the search on this website is not working with me. Here's the deal...

I am on a firmware version from the end of last year, and have not upgraded since, as I was concerned about not being able to take off in a NFZ. Now, before you Nancys get on my case about flying in a NFZ, I have permission from the airport....

My questions is, if I have not upgraded my firmware since they started this rule, is there something in the DJI Go app that is preventing me from taking off? I was using a non-internet-connected device before, and never had issues. Now, I am using my phone on LTE, and it prevents me from taking off at all in red zones. My other question is, if I have permission from the airport, how long does it take to get the no take off allowed, overridden by DJI, if I contact that flysafe email? Is it instant, or do they get back to you after X number of days/weeks/months. I have another trip coming up that I have permission for an airport, and I don't want to be stuck waiting for DJI to get back to me on this, before my trip ends.

Any input is greatly appreciated!

I'm in a NFZ area and I can fly after the latest updates. It's even easier than before actually. Now, all I do is check off a couple of boxes and away I go. I think not updating is causing problems for you? I also use my LTE-only device but that should not be a hindrance since flights can be made in Airplane mode.

... use again a non-internet-connected device!  Or simply switch phone to airplane mode...

Up to 24 hours.

What app version? You'll need to logon to Dji Go4 and you should be able to fly again, it's a one time activation.

Ah, ok! I'll try these suggestions. Thank you all very much!

So you guys all think it is safe to just update to the latest firmware too?
