I’m having trouble using Grid Mission on my iphone. All the settings are fine except for the " S1 switch position correct" option which has an X on it. I’m even flying in a place where 12 satellites are recognized.
I’m using a Phantom Vision 2 Model PV330. I have an iPhone 5S.
It is the same as this problem this man is describing on youtube: https://www.youtube.com/watch?v=hwIgBhvDNMM
Any troubleshooting suggestions would be appreciated.
