Still works as before, but problems exporting in 4K

Ive been using this app for years, and its hasnt disjointed. Nice to see it now one buy for both the iPad and iPhone, good addition going universal.
But it needs an update, Im getting an error on exporting in 4K, something about not being compatible with my OS. Hmm, its the latest iOS. Content was shot also on latest iOS in 4K on iPhone 6S. Video is being edited on iPad Air 2 and I know iMovie can export 4K. So my guess is something with the app needs updated. I also transferred the file from the phone to the iPad using airdrop. Most likely others will be doing the same. Please update and thanks for the continued support and features.
