I wish someone can explain to me how its now working so I know for the future but after trying to Unlock the NFZ in the app and being told I didn't need to for that area I returned to the park where twenty minutes earlier I wasn't allowed to take off,I was this time

besides trying to unlock the NFZ I also checked to see if I had the latest firmware installed and I did but I still hit the "refresh" just in case
So I'm guessing you have to log into your acct. every month or two just to be able to keep flying ? I'd say its over a month since I logged in..
I tried logging into the "Unlock NFZ"/DJI app via personal hotspot using the tablet I fly with but it doesn't allow it ,it ask for a wifi provider that you use out of a list of five all of which I dont use .
