I'm still newbie with my Mavic Pro, and perhaps there's a setting, that can avoid this behavior. But have a look:

In the warnings of Go4 App I saw, that the Active Track goal has been lost, and searching had started. But then, obstacle avoidance seems to be not working anymore. Go4 App is 4.3.20.

Thanks for hints and comments

Hi Tony,
unfortunately I've read your reply just now. I'll check my forum user settings later for improvement.
I didn't sync anything in the past, and made a first attempt now. But I couldn't localize the special flight record of this Active Track crash.
And in many cases I'm using the Go4 App only for initial setups and starting, then switching to GS Pro and doing Waypoint missions and an initial PhotoMap attempt. GS Pro seems to not show any Flight data at all, but perhaps I still need to learn that.
