Wondering if I can move it to only be shown when a user taps into the listing?
If I include an app preview does it have to be the thing that is displayed when users see my app store listing from the search results page?
Ideally I'd like 3 of my portrait oriented screenshots to be shown on the search results page
While the dev can choose which of their app's screens are portrayed, App Store interaction varies by device and is under Apple's control.
And while a Preview video is optional, again, the dev has no direct control over when/where/how it is presented to users in the store.
