Hello, Additional information: the same subscription works correctly with StoreKit local testing in Xcode (StoreKit configuration file). The product is returned and the purchase flow behaves as expected. The issue only occurs in the App Store sandbox via TestFlight, where the same product ID returns an empty array. This suggests the implementation is correct and the issue may be related to App Store Connect or sandbox availability. Thank you.

Hello, Thanks for your response and for pointing me to TN3186. I have carefully followed the troubleshooting steps, but the issue still persists. Below is a detailed summary of the current situation. Configuration status: The auto-renewable subscription is fully created in App Store Connect Product ID: sylvoy_sylvoy_premium_v2_monthly Status: “Ready to Submit” Pricing is configured and available across regions The subscription is correctly added to the app version under “In-App Purchases and Subscriptions” StoreKit is properly implemented and getSubscriptions is called with the correct product ID Testing performed: Tested on a physical device (not simulator) Logged in with a Sandbox Apple ID Logged out and re-authenticated the App Store account Reinstalled the app multiple times Waited for propagation delays (over 24 hours) Verified that no StoreKit errors are returned (only an empty product array) Confirmed that bundle ID and product ID match exactly Current behavior: getSubscriptions() always returns an empty array No products are fetched from the App Store No error is thrown, suggesting the products are not available rather than failing Important observation: This is the first subscription for the app. App Store Connect displays the message: “Your first subscription must be submitted with a new app version.” At the same time, the subscription still shows: “Finalize before submission” in the localization section Even after editing and saving localization fields, this status does not clear, and the “Save” button is sometimes disabled unless a forced change is made. Suspicions: The subscription may not be considered fully finalized internally by App Store Connect As a result, it may not be exposed to StoreKit in the sandbox environment There may be a state inconsistency where the product is neither fully draft nor fully available Clarifications needed: Can a first subscription be fetched in the sandbox before submitting an app version for review? Does the “Finalize before submission” state prevent StoreKit visibility, even in sandbox? Is there any internal validation or propagation step that could block product availability in this state? At this point, the configuration appears correct, but the product is still not returned by StoreKit. Thank you for your assistance.
