Summary of Issue:
Attempting to fly a plan and getting “Unable to start mission”, with no hint towards the potential root cause. All items in the check list are green and drone gets no error while initialising.
This is a location that I had flown a few weeks before with a Phantom 4 Pro. After this error was shown, I was able to manually fly the drone without issue using DJI Go 4. After the manual flight, I was still getting the same error when I tried again to fly the plan. The same drone and iPad flew a different mission at a different location the day before.
The only thing that I can think could be the root cause is that it was a very hazy, overcast day and maybe the GPS signals weren’t strong enough. However, it would have been good to have a message from the app that indicated a potential root cause for why the mission could not be started.
