I recorded two flights today and from them are in the GO app manager so I can create a short "music" video.  A third flight I did the video is on the SD card but not in the GO app, and it won't upload.  Also any previous unedited videos are not in the app anymore either.  Not sure when they left.  Any ideas???  Using most up I date iOS on iPhone 5s
