Canceling an app does it delete the data
We gave our daughter a new iPhone. I transferred the data via an iCloud backup from the old iPhone. I noticed the VideoStar App (the only app) is taking a long time to update (it has been several days), everything else was fine. When I press on it it is giving me an option to "Cancel Download". If I select to "Cancel Download" will it delete the data (the videos created by VideoStar)?
iPhone 11, iOS 14
