After updating to macOS 14 I am unable to sing in to a test Sandbox account in the App Store app. Steps to reproduce: Open macOS "App Store" app Go to settings (CMD + ,) If already a sandbox account is listed in the bottom section then sign out Click "Sign In" button in the bottom section Follow authentication prompts Current behavior: Authentication completes, but the state of the bottom section does not change. Only the "Sign In" button becomes active again. Expected result: Authentication completes and the bottom section displays current Sandbox user.

While testing the purchase of renewable subscriptions on App Store's sandbox environment we have observed that defining subscription availability (either restricting to specific countries or making it unavailable) has no effect. No matter what is the purchasing Sandbox Tester's assigned region or even if the product was marked as unavailable - always every product defined in App Store Connect is returned when fetched using StoreKit 2 API (Product.products(for:)). Due to the described behaviour we are not able to test different sets of products being available for specific regions. Note: The testing was done on app that is not yet published and the products as well were not reviewed - they all have "Ready to Submit" status. The app was built from Xcode (TestFlight distribution was not used). -- Question 1: Is that an expected behaviour? Question 2: When testing TestFlight distributed app will the availability be respected? Question 3: Is the subscription's status in App Store Connect ("Ready to Submit") related to how it behaves? Is the behaviour varying when testing on Sandbox or using TestFlight?
