When I take a photo, the screen goes blank and the a swirl goes around the shutter button on the screen for a few seconds and then it shows a DJI logo before coming back to show me the live view. It doesn't actually capture anything. Same thing in video. Tried different sd cards, re formatting etc. Updated to latest firmware, still same issue. Will not trigger camera or video either by controller button, nor from iPad Mini DJI Go app screen. Even tried an Android device to make sure, same problem. Any thoughts?
