Camera didn't take pictures

I am using a Phantom 4 with most recent firmware and Ipad with drone deploy 2.0.8. Flew the mission…didn’t the pictures flashing on the screen and nothing on the card.
Any ideas. (the previous mission is captured the pictures just fine)

Did you see a message pop up telling you that the camera is probably not capturing images? It should show up if we see that images are not working.
