Can't Add Localization in iTunes Connect

I have a question about iTunes Connect: When I click "Manage Localiza开发者_开发技巧tions" on the page of my iPhone app (which is online, not in Review or something), I am not able to add a new language.

Does anyone know whether you can only add localizations when creating a new version of the app? Or did I overlook something?

does it say this?

You cannot add a new language from this page because your app has either already been approved or is currently in review. To add a new language, you must submit a new version of your app.

So if online means "in the app store" then yes, a new localization is only possible when you submit your next version.
