HI there. I am new to this forum so not sure if I am asking the question in the right place. I have 2 questions. First one is to ask if anyone knows how I can fix the problem of my DJI app wanting to refresh at the most inconvenient moments when you don't have Wifi. I don't fly it unless I can see where I am going on my iPhone. Second question is when I download the photos and vides to my Mac from my Drone, a grey line comes up and an X on the top left hand corner of some of the photos. Not all. Just some. Can anyone help me understanding the reason? I can still open the photos but just wondering why some have it and not others. Sorry if these are stupid questions.
