Hello - I had some problems recording video and pictures this weekend. I was out in a cool wilderness area and took some great shots but I couldn't record video. I would hit the button on the DJO Go app and it wouldn't start the recording. It seemed like it was taking picture just fine. I shut down DJI GO and started Litchi and it looked like it was recording and taking pictures. I get home and there was nothing on my SD card. I have a high end fast Samsung 64GB SD card. So I reformatted it and took it out and it worked. I took the pictures and video off of it. Put it back in the Bird and it said that the SD card wasn't formatted. So I took it out, reformatted it on my computer, put it back in and it worked. Not sure what the problem is. It has never done this before. Don't know what is causing this problem but it sure is disappointing when you think you are getting some great shots and then come home to find nothing on the card. Thoughts?
