The other day I was doing a survey using my DJI Mavic Pro and drone deploy account and the battery needed changing. I landed the drone safely and changed the battery then continued mission. The drone then reached mission altitude but then decided to return to home. I repeated this step multiple time and I have done hundreds of missions with my drone and drone deploy account, but this has never happened before. I had to redraw the map out, covering the remaining terrain I needed to picture.
Do you know why this could be?
