Localiji uses the documented screenshot display types and preview display types. If any of those documented types are missing in Localiji, please let me know. Otherwise, it would be Apple’s responsibility to update the App Store Connect API.
Unfortunately, Apple doesn’t seem to keep that part of the API in sync with the new devices they present. To add to the confusion, some display types in the API (and used by Localiji) are automatically associated with a different display type in App Store Connect. For example, the iPhone 6.7″ display type in the API is associated with the iPhone 6.9″ display type in App Store Connect, and the iPad Pro (3rd Gen) 12.9″ display type in the API is associated with the iPad 13″ display type in App Store Connect.
I created some posts on the Apple Developer Forums about the outdated API, but unfortunately Apple never responded:
