Q: I cant export and share my video from imovie in my 6splus

SInce the latest update I am having the same trouble with my iPhone 6. Tried deleting iMovie and reinstalling and still cannot upload.

what worked for me was exporting the movie without any previously added. audio files (from music library, etc), then after that file exported i put that file into imovie and added the audio files again, then successfully exported that one.
