Apple announces that App Store review team will work through holidays, but review time might be increased.
The busiest season on the App Store is almost here! Make sure your apps and games are up to date and ready in advance of the upcoming holidays. We’ll remain open throughout the season and look forward to accepting your submissions. On average, 90% of submissions are reviewed in less than 24 hours. However, reviews may take a bit longer to complete from December 22 to 27.Apple Developer
