Apple appears to be removing a large number of apps from the App Store that have not been updated for “a significant amount of time” (via The Verge).
According to an “App Improvement Notice” email sent to affected developers, Apple is removing apps that have “not been updated in a significant amount of time” unless developers issue an update within 30 days:
“This app has not been updated for a significant amount of time and is scheduled to be removed from sale in 30 days. No action is required for the app to remain available to users who have already downloaded the app.
You can keep this app available for new users to discover and download from the App Store submitting an update for review within 30 days.
If no update is submitted within 30 days, the app will be removed from sale.”
