You only need to log into your DJI account on the Internet every few months. It was just a coincidence that you needed to log in when you did - nothing to do with the change of location or the TFR.
Your controller connects at home because you are within range of a wifi signal.
Not so in Florida
No .. as explained in post #6
Your drone doesn't care where you flew last.
What they are saying is... you could be on the moon with Darth Vader, and as long as you log in to your DJI account with a valid connection while on the moon, then disconnect from the wifi completely, you could fly your drone there immediately...
These are my 4 favorite AG A1 videos so far. I think the DJI Avata 360 will be able to recreate the videos but I don't think the features will be there.
