I updated to the newest software today and my camera size is stuck on 4:3 now and there is no option to change it.....

So i recalibrated the gimbal and it let me adjust it.

Which Version of Software did you get and was it on Android or MacOS ?

Hi there JrFTW, thank you for reaching us out and my apologies this has caused you. I'm glad that recalibrating the gimbal resolve your issue. For any issues related to Camera you can do this, reset camera settings and gimbal calibration. Always fly safe and thank you for your support.

I had the same issue 1.2.0 when it was first released then a quickly an update to the app was released that fixed this.  It is working for me on IOS 1.2.0 & 1.2.1.

4:3 is the full resolution for the camera.
Why would anyone want to shoot in anything less?
