iTunes Connect -- the portal through which developers submit and manage content for the App Store, iTunes Store, and iBooks Store -- will this year see its holiday downtime for app submissions run between Dec. 23 and 27.
Any new apps or updates should be submitted and scheduled in advance, Apple informed developers on Tuesday. People will still have access to other iTunes Connect features during the break.
The company further noted that in the iOS 11 App Store, developers can insert promotional text up to 170 characters long in case they need to alert customers about events and upcoming features.
Apple regularly suspends app submissions for a brief time every year while staff are on vacation. The Christmas holidays are actually one of the busiest periods at the App Store, since many people are receiving new iPhones and iPads as gifts, but much of it is automated apart from the review system.
