Hello.This is my first post and this is my second mavic mini fcc version.Ordered on amazon.The drone seems to have extreme difficoulties in finding gps sats.It starts normal in an open space and then as soon as reaches some altitude over 50m gps looses signal and give sensor error.I have calibrated it normally.I have tried many locations by now but they are all in the city, although i have never had gps problems with my old mavic mini in the city which i crashed acciddentaly,i mean i could start it inside my 8-th floor apartment and then as soon as it got out it would find the gps but this new one does not.The product has been activated with dji refresh but i dont know if i should do more tests,return it back to the seller or just return to dji since i have the refresh care.Any opinion would be appreciated.Thanks
