Having a lot of success with the Anafi easy to fly and lots of fun. About 30 flights so far however occasionally when I power up the drone the green battery lights come on the fan starts but the blue light on the bottom stays dark. Then I cant shut it down without removing the battery. This usually fixes the problem but sometimes it takes two or three times to resolve. This happens about 1 in 10 times I power up. Anyone have similar issues and suggestions to fix the problem.
