iTunes Connect Holiday Schedule
The busiest season on the App Store is almost here. Make sure your apps are up-to-date and ready for the holidays. New apps and app updates will not be accepted December 23 to 27 (Pacific Time), so any releases should be submitted, approved, and scheduled in advance. Other iTunes Connect and developer account features will remain available.
With the new App Store on iOS 11, you can let customers know about promotions, upcoming features, and events within your app at any time using the promotional text field. Your app’s promotional text appears at the top of the description and is up to 170 characters long.
