Hi.
I have chosen a name for my new app, which isn't available in "English U.S.". When uploading it to TestFlight using Xcode, I get.
The app name you entered is already being used. If you have trademark rights to this name and would like it released for your use, submit a claim.
I changed the primary (and only) language from "English U.S." to "English U.K." and the app name is now accepted by App Store Connect. The app is supposed to be worldwide available and doesn't target any specific geographical region. It's also only available in English (no localizations).
Are there any disadvantages using "English U.K." i.s.o. "English U.S."?
What are the differences between both when it comes to App Store presentation, ranking, search, ...
I don't really see why Apple offers 4 English languages. Every style understands the other one, despite some minor spelling differences.
