Sorry, this type of video cannot be saved to this device.
I have an iPhone 7plus (ios10.3.1) and i have consistently made movies and promos using iMovie on my device and where the mobile app is limited, i do the work on my laptop. I have never had an issue rendering files that i would then airdrop or dropbox to my device until recent. I have tried rendering in different/lower resolutions to no avail, i have over 100 gigs of storage on my device and a tb of iCloud space so space isn't the issue either but for some reason, the files that are from iMovie will not download to my device. Can someone please help me as this is really hurting my business and driving me nuts!
iPhone 7 Plus, iOS 10.3.1
