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.
My Apps > App Store > App Information > Primary Language

UPDATE: 

Please check Localization in your project. Maybe only "French" is showing?
