I want to add new languages + localized ones to My Apps
I have been getting this error for about a week for all applications and I am unable to add new languages to my application.
We are temporarily unable to save your changes. Please try again later.
When you add localized languages, remove any screenshots that fall into the first language (even if they are the same ones that you intend to use), then reload them all again.
(Use delete all ScreenShots - when entering a new language page !!!)
