I just updated the RC Pro, the Air 2s and the Fly app to 1.7.8 SUCCESS!!! It appears that Airsense no longer crashes Fly. I will have to check again tomorrow, no planes were flying tonight.
The Cine mode expo works great!!! Finally!
I will further test tomorrow, but it seems that the C N S mode maintains after switching off the controller.
One big thing is that on the 2S, the rear LEDs no longer flash red, the front still flash green.
I will update tomorrow as necessary.

Hello there Mobilehomer. Good day and thank you for sharing these information about the new DJI Fly v1.7.8 application update. Again, thank you for your support and keep flying.

Thanks for sharing!

Perfect. I have just finished first flight with 1.7.8 Everything ok. Waiting for my new DJI RC to arrive and test it.

That's great news Mobilehomer.    I was still on 1.70 to avoid the App crashes with AirSense.
