My Air 2S iso is stuck in auto. I cannot set manual iso. I was able to set manual iso previously but I noticed today that iso is stuck in auto. I use an iPhone 6s to fly. I also shoot videos in D-Log. I have tried to reset my camera settings but nothing seems to happen because my settings are still the same. This is a replacement drone DJI sent me. Has anyone experienced this with their drone? The iso is on auto and the button is greyed out.
