I have 50 flights, but recently, my DJI GO App has not been keeping the thumbnails of the images I took during flight. I realize that if you don't take any images, there won't be any thumbnails, however, I have taken several images, and all I have are blank images in the app. I will post a picture of what I am talking about. I just don't understand why they aren't showing up in the recent flights? Any ideas? Thank you!
