isn't that the one from 3/3/17
I am not sure... I just bought the drone yesterday,
and was going to fly it for the first time today and it asked for the update first the app and then it went through the cycle
Updating Drone and asked me to move the connection from the remote to the drone direct - went through one shot - around 30 minutes total update time
Went through camera / board / gimbal / battery / controller all of the above - Completed with no hitches
Shut down the drone and restated it flew it around for about 15 minutes straight without any hitch or weird issues - app was fine to
So far so good.....
