I am having sporatic issues with the camera shutter button on my Smart Controller.   I take a lot of action shots over sailboat races and many times nothing happens when I push the camera button to take a picture.  Sometimes I have to push it 6-10 times before it takes the picture.  This is becoming a real problem when I am trying to get perfect action shots above a fast moving boat.  Any ideas what I can do to resolve this?

Have you checked the firmware on the drone with DJI Assistant?

Just as an asside, I seldom take stills now. I video in 4K and stills extracted from the video are sufficient for my needs, plus there are 30 frames taken each second, so are aren't going to miss a certain shot

Thanks, I will try both.   Appreciate the help sir.
