If you upload a preview video, it must show real, current app functionality captured from an actual device — not a concept animation, another app's footage, or a composited demo that doesn't reflect what ships.
Marketing teams sometimes produce a preview video before the corresponding feature actually ships, and it goes stale against the real build.
"Your app preview does not accurately reflect the app's actual user interface and functionality, per guideline 2.3.4."
Guideline 2.3.4 concerns app preview videos. A preview has to show the real app, captured on a device, as it works now. Concept animations, composited demos, footage from another app or videos that run ahead of what has shipped are not acceptable. Marketing teams that produce a preview before a feature is finished often run into this.
App previews appear at the top of a listing and often decide whether someone installs. If a video shows features that do not exist, or footage that is staged rather than captured, people download an app expecting something it cannot deliver. Apple requires previews to reflect the real app so that the storefront stays a reliable guide, and so that the effort of honest developers is not undermined by more polished but misleading competitors.
Yes, within Apple's rules, as long as the app's real interface is visible.
No. It is optional.
Only if the old one no longer represents the app accurately.
