Yes. I upgraded firmware immediately after powering up for the first time. I was running the current firmware when I experienced the issue. I should add that I already had the app installed due to using it with other drones in the past.
Thanks for the official note - I'm sure it will help someone. In my case, this was a brand new Mavic - just out of the box this afternoon... No settings to reset! :)
Yes! Success - just before dusk, I was able to re-install app and take off and fly to the limits set in the app. I tried literally everything else I could think of, so uninstalling, reinstalling app on my phone was the fix.
Same problem here on a brand new Mavic. I've run a lot of DJI drones, so I know about Beginner Mode. I've triple-checked that. I've also tried the sign out/in trick and the compass calibration. No dice.
