Ive checked the maps and im not in a NFZ

Yet my Mavic keeps flashing a c1 warning at random , normally nothing happens and it goes away in an instant, yesterday however, it emergeny braked  and i couldnt move it back to me for a second, went away and did it again, went away and i got it back landed and re checked , everything was clear with the maps.

Thhnks

NATS app only shows ground hazzards  and yellow warnings also

I under stand  Class C is from Flight level 195 to FL 245

So shouldnt have issues, but whats C1?

Sir, please ensure that you are not in restricted area or NFZ, here is the link for your reference: https://www.dji.com/flysafe/geo-map Or you can check if your database is the latest version and flash the map when you have Internet access. Thanks for your support.

Im not....

C1 is the button on the bottom left side of your controller.  Is it not setup or possibly set to some unusual action on the Rc?  I would check that first.
