I just put my app on the store for pre-order. I wanted to localize it to Spanish (don't ask me why 😅), so it should be supporting English (primary language) and Spanish. However, on the App Store, it thinks that my app only supports Spanish. How do I fix this in App Store Connect (or wherever it should be fixed)? Thank you so much for the help!
If you are using String Catalogs for localization, one way to workaround this issue is by having at least one string in the String Catalog translated to some non-default value in English. This can just be a manual string that is never referenced in code or used at runtime.
This will force the generation of an en.lproj in your app which should cause the App Store to detect English as a supported language.
