Apple notifies developers regarding updates in App Store Review Guidelines.
Added 2.3.13. “In-app events are timely events that happen within your app. To feature your event on the App Store, it must fall within an event type provided in App Store Connect. All event metadata must be accurate and pertain to the event itself, rather than the app more generally. Events must happen at the times and dates you select in App Store Connect, including across multiple storefronts. You may monetize your event so long as you follow the rules set forth in Section 3 on Business. And your event deep link must direct users to the proper destination within your app. Read In-App Events for detailed guidance on acceptable event metadata and event deep links.”Apple Developer
Deleted from 3.1.3. “Developers cannot use information obtained within the app to target individual users outside of the app to use purchasing methods other than in-app purchase (such as sending an individual user an email about other purchasing methods after that individual signs up for an account within the app).”
Added 5.1.1 (x). “Apps may request basic contact information (such as name and email address) so long as the request is optional for the user, features and services are not conditional on providing the information, and it complies with all other provisions of these guidelines, including limitations on collecting information from kids.”
Developer:Review the updates, be ready to implement features based on new available approaches.
QA engineer:Business as usual.
