Need some help on the dji go 4 app editor ive got some video's that ive edit but it says failed to save on all my videos and its not even 5min long, any suggestions?

Sorry for the trouble. It may relate to the mobile device or APP version that you are using. Please try to download the video from SD card and then edit or reinstall APP or change a different mobile device. Kindly back up your files and sync your flight records before you uninstall the APP. Please take note that the files saved in your SD card are better compared to the cached files saved on your phone.
