Thanks for your answer. I’m observing the same behaviour in the sandbox environment. Here are the steps I've done if that helps: I created a Sandbox account in App Store Connect: I cleared the Purchase History for this tester and set the Subscription Renewal Rate to Monthly Renewal Every 3 Minutes. I created a fake App in App Store Connect. I configured a subscription group in App Store Connect for this fake app and added a monthly subscription to this subscription group (this monthly subscription is in Ready To Submit stage after I added enough meta data). I run the app without using the Xcode config file: the product added to the app on App Store Connect is correctly loaded by the app and I can subscribe to it using the sandbox account on a real device. I leave the app opened and I receive the transactions when the app is running. I hard quit the app and wait enough time for virtual renewals to normally be created (for example I wait 30 minutes, which should have renewed the app 10 times based on the Sandbox tester account setup for subscription renewal rate). I launch the app again and fetch the last transaction for this subscription: it's still the one downloaded 30 minutes ago, before the app was quitted. I fear the behavior is the same in a production environment so I fear I missed anything and don’t want to ship not working subscription management in my app.

Thanks, I think a bug in Xcode made it hard for me to understand that a transaction for a free trial is a transaction with the trial duration (I thought it was included in a normal transaction). When running in Simulator, the introductory offer is not taken into account and the first transaction has a duration equals to the subscription period (see attached screenshots). It's working correctly on a real device. If you want to try it by yourself, I submitted a feedback FB9789041 few minutes ago: StoreKit 2 • introductory offer duration ignored in Simulator, where the expirationDate is wrong (correct on real device).

It's working normally with Xcode Version 13.1 (13A1030d) and iOS 15.0 (simulator). I think it's a bug, I'll fill a report for that.
