You need to log in from time to time (not sure of how often) to avoid being restricted in height and distance. This happened to me once in a remote part of Idaho.
I have been logged out by DJI from time to time too over the years, I don't remember how many days of inactivity or whatever they use. I suppose you could check the settings on your device or whatever to make sure your account is logged in that...
I found my original question to DJI. Here it is: The storage full message turned out to be because my 8gig internal memory was full so I fixed that. Then no more message.
I flew my Mavic 3 Pro for the first time in over 4 months. I have to admit...
I know I've flown thousands of times with no internet connection. I going on a trip on December 15th so I want to make sure everything's working properly. Before Sunday I hadn't flown in months. My mini 3 pro did ask me to login today.
