There is an issue with StoreKit. The line let products = try await StoreKit.Product.products(for: ids) doesn't always work correctly. Sometimes it returns an array with the correct data, and sometimes it returns an empty array. I'm passing the correct ids to products(for:). This problem only occurs when using the sandbox environment (in TestFlight builds). In the App Store version, everything works fine. StoreKit configuration is none. All IAPs are approved. Everything was working fine before this. The problem was discovered on May 1, 2025.
