I am new to flying drones and my new Anafi. I noticed the last two times I used it there was a ? showing instead of the distance? The vertical height works fine. Any ideas why it does this?
Did you let the Anafi GPS signal go green before you took off? If not then it would not know where it's home point is and would not RTH if you ever needed yo use it.
I would suggest that you read the online User Guide from the Parrot website.
Most likely you're using an ios device. Unlike android devices, most ios devices don't have gps antennas. Or perhaps you didn't have gps (or 'location') turned on.
