Hello
It looks like Apple made some changes on the way language codes are managed on their side and I cannot find the new codes for Chinese languages.
Has anyone had some luck in finding the correct language code? I have tried every variation I could find of Simplified and Traditional Chinese language codes, but application loader always returns the error: "The following header columns names are invalid: description zh-hant, displayed name zh-hant, displayed name zh-hans, description zh-hans"
