Question: Apple recently released a new version of iTunes Connect.
I just want to change the primary language of my app, but the documentation (<https://developer.apple.com/library/ios/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/Chapters/DisplayInMoreLanguages.html> at the bottom) is now deprecated.

Anyone solved this problem?

Answer: 
I was able to change the primary language after being accepted by the appstore. 

Despite what the documentation says, it seems that changing the primary language is impossible in "Prepare for submission" state.
I found a way to make it work without having to get accepted by the App Store.

1. In Localizable Information, click on the language and choose a new language you want to add as primary language.
2. Very important. **Hit Save** at top right corner.
3. Go down to General Information. You will find now that Primary Language becomes a drop-down menu with new language that you just added. You can proceed to change your primary language and then Save.
