As it does every year, Apple is closing iTunes Connect, Application Loader and iTunes Connect for iOS for Christmas. The services will be unavailable from Monday, December 22, through Monday, December 29.
The closure means developers will not be able to submit new apps, updates or in-app purchases. New apps and updates will appear during the Christmas period but they’ll need to be submitted by December 18 to be approved.
