DJI finally admitted and announced DJI GO app with compatibility issues on iOS 9. Unfortunately, there is no further details about what sort of "minor" compatibility issues so far.

Personally, my Phantom 3 continues to fly like a free bird.....
Definitely experiencing control and video lag at distances where I didn't before.
It sounds like you tried to get rid of the issues and possibly they are minor?As a third-party developer of FPV Camera app, we were well aware of some obvious compatibility issues since iOS 9 beta has been around for months. We did our best endeavors to address those known issues as much as possible weeks ago, though it couldn't iron out everything.
DJI has a lot more resources, and hope they will address all the issues properly.
Per the feedback from FPV Camera users, it works great on iOS 9 and iOS 8, though there are plenty of rooms for improvement. Apple claims iOS 9 is 20% fastest than iOS 8 on the same device, IF the app is optimized for iOS 9.It sounds like you tried to get rid of the issues and possibly they are minor?
The issues with DJI (if you have them) range from severe lag to loss of connection at short ranges to the inability to fly. Those are not minor issues.
