Each year, Apple closes iTunes Connect for a week during the holidays to give its App Store staff time off. This year, iTunes Connect will be closed from December 23 to December 27, inclusive. While iTunes Connect is not available, Apple will not accept new apps or app updates, which means that all price changes and app shipments they must be sent before that date.
Developers tend to offer discounts and promotions before the App Store closes during the holidays, and those sales remain available until the App Store reopens at the end of December, starting on December 28. Although application submissions for review in the App Store will not be available, other iTunes Connect tools will remain accessible to developers during the holiday period.
iTunes Connect is the portal that Apple makes available to developers so that they can send the applications they want to publish in the application store, in addition to updates, developers can also resolve any type of doubt that is related to the guidelines that all applications must comply with in order to be available to everyone.
The closure of this platform for holidays will not affect at any time the operation of the App Store and Mac App Store, it only affects all those developers who want to publish their applications for Christmas, and if they want to be available for compulsive Christmas purchases, they must submit your applications for review a week before, at least.
iTunes Connecte is the only Apple platform that will stop working for Christmas, since the rest of the services and platforms, whichor depend directly on personal supervisionwill continue to be available.
