When I use iMovie on El Capitan, the 'iMovie Theater' it keeps saying 'Turn on iCloud Drive' in the upper left had corner. However, i have iCloud for iMovie turned on. I try to turn it off and on several times in the iCloud settings. Is this a known issue for it in El Capitan? is there another setting that I don't know about? No movies show up in the 'IMovie Theater' even though I have around 6 or 7 on my other devices. (Although I usually have problems with the iMovie Theater not syncing correctly between all my devices.
