Yes, I'm seeing that now on m3 cine
Reformatted, no change
Nb: if you reformat, make sure you have access WiFi of hotspot, as you'll need to log into your dji account before being able to fly past 50m
I had it show up when I was flying last week and I had shot lots of videos and I was concerned I would have corrupted files. When I got home, I downloaded everything, and all my video files were fine. I formated and I am going back out today to fly to see if it still gives me the same message.
