Flying yesterday at a spot that I had already checked out I got a message on the DJI app that said "Your aircraft has entered a warning area...Please fly with caution" I had checked Kittyhawk and Airmap before flying and both were green...I was at 47ft AGL...I later moved to a new location where I knew I would need a LAANC which I obtained and was good to 200ft...No messages period even when I approached the 200ft mark...Any ideas on why I got that message? I have to fly there again and want to be sure...Thanks to all who respond.
