I am trying to upload an App Preview to App Store Connect for a macOS app. I created the preview using iMovie as an "App Preview".
When I try to upload the app preview I get the message "One or more of your app previews are too long".
The preview is 4 min 48 sec. It is 208 MB in size. MP4 format.
I see in the requirements for app previews that they that must be under 500MB, which mine is. I don't see any limitation on the length of the preview.
Any thoughts?
