The Screenshot specifications page lists iPhone Duo as an iPhone screenshot size: Outer display: 1398 × 2034 and 2034 × 1398 Inner display: 2007 × 2853 and 2853 × 2007 https://developer.apple.com/help/app-store-connect/reference/app-information/screenshot-specifications I cannot find a way to upload them. In App Store Connect, the App Previews and Screenshots device selector on my app's version page does not list iPhone Duo. The only iPhone options are the existing display sizes. In the App Store Connect API, ScreenshotDisplayType has no Duo case. The largest iPhone case is still APP_IPHONE_67. I checked the current reference: https://developer.apple.com/documentation/appstoreconnectapi/screenshotdisplaytype My questions: Where in App Store Connect do I upload iPhone Duo screenshots? If the option is not open yet, is there a ScreenshotDisplayType case for Duo that I should use through the API instead? Thanks.
