Begins January 24, 2025
The SHA-1 intermediate certificate used for signing App Store receipts expires on January 24, 2025. If your app performs on-device receipt validation, make sure it supports the SHA-256 algorithm; alternatively, use the AppTransaction and Transaction APIs to verify App Store transactions.
