Worked fine on Sunday....
Last night, IOS wanted to run a new mission no video on Litchi.
Restarted all, reloaded mission of the hub. I could run the camera, motors etc, no video.
Shut down Litchi loaded DJI-Go all there with camera.
Restart all again, still no video in Litchi, decided to run it anyway, pressed record and told it to run the mission. Error wouldn't take off.
Restarted all again, there was a Litchi update on IOS about the 7th I think and now as of 4/18/2017 an update for Dji-Go.
Did all and restarted all, all worked, ran the mission.
I think the three clowns says it all
