StoreKit Product Request Times Out in TestFlight (macOS) Despite Successful Server Connection

Product Timeout, In App purchase is approved in App Store Connect. The Product ID and Bundle ID match.

Environment

  • macOS App in TestFlight
  • Bundle ID: com.streamtime.StreamTime
  • App Version: 1.1 (Build 51)
  • StoreKit 2
  • Product ID: com.streamtime.premium
  • Status: App & Subscription Approved

Issue StoreKit product request (Product.products(for:)) consistently times out after 60 seconds in TestFlight, despite all connectivity checks passing. The same code works perfectly in Xcode with local StoreKit configuration.

Diagnostic Results ✅ Successful checks:

  • App Store connectivity (HTTP 200 from buy.itunes.apple.com)
  • Backend API connectivity (HTTP 200)
  • StoreKit 2 API available
  • AppStore.canMakePayments: true
  • Valid receipt exists
  • Bundle ID matches
  • Product ID matches approved subscription

❌ Failing:

  • Product request times out after 60 seconds
  • No products returned

Code Implementation

// Direct product request (fails in TestFlight)
let products = try await Product.products(for: ["com.streamtime.premium"])

Logs 🔍 App Bundle ID: com.streamtime.StreamTime 🔍 Product ID: com.streamtime.premium 🔍 AppStore.canMakePayments: true 🔍 Apple Store connectivity: HTTP 200 🔵 Direct request for product ID: 'com.streamtime.premium' ⏱️ Direct request start time: 2025-08-30 10:21:32 +0000 ❌ TIMEOUT: Product request took longer than 60 seconds

What I've Tried

  1. Removed manual in-app-purchase entitlement (per Apple's guidance)
  2. Using automatic signing
  3. Verified subscription is approved in App Store Connect
  4. Using Sandbox Apple ID in TestFlight
  5. Verified all network connectivity

Questions

  1. Why does StoreKit timeout only in TestFlight when all other connectivity works?
  2. Are there additional configuration steps needed for macOS apps vs iOS?
  3. Could this be related to the automatic in-app purchase entitlement?

Any guidance would be greatly appreciated as this is blocking our TestFlight validation.
