We have submitted many releases with iPad screenshots and app preview content.
App Connect ingests our content and shows it in media manager. When the app is released the storefront doesn't show our content, instead the app store shows a years-old collection of content both in the store search results AND on the app detail page. Basically they have chose random content and do not allow us to overwrite it. We've seen this on two different apps.
Anybody else? We can't be the only ones seeing this.
