I have in my application a video as an App Preview of my application. I have my game localized with up to 10 languages.
The thing is, I don't want to show this AppPreview in French and Italian, but I can't find any way to filter this, looks like it is shared for all languages.
Do you know if it's possible?
It's not possible to have different "versions" of your App Preview, i.e. you cannot even delete it for specific languages. What Linus is referring to only concerns screenshots.
An app preview demonstrates the features, functionality, and user interface of your app or game in a short video that users can watch right on the App Store. Each preview is between 15 and 30 seconds long and appears in all countries or regions where your app is available. For details on capturing app footage, see Creating Videos for App Previews.
