## Timeline of updates

- **investigating** 2026-10-21 12:51 UTC: We are seeing elevated errors when validating purchases made in Apple's sandbox environment, including TestFlight builds. Since about 06:00 UTC, most sandbox purchases and restores on iOS, macOS, and other Apple platforms are failing to validate, so test purchases may not unlock entitlements. Purchases made with real money in production apps are not affected.
- **resolved** 2026-10-21 16:12 UTC: The incident has been resolved. Apple Sandbox App Store API is correctly processing requests.
