I'm testing auto-renewable subscriptions with a local .storekit configuration in Xcode 27.2 (27B52). With the same app and configuration on iPhone 17 simulators, I get different results on iOS 26.2 (23C54) and iOS 27.2 (24B8117). Set SKTestSession.timeRate to .oneRenewalEveryThirtySeconds, then purchase an auto-renewable subscription in the app with StoreKit 2. Wait for the original period to expire and the first automatic renewal to appear. Refund that renewal using SKTestSession.refundTransaction(identifier:) and wait for the app to receive the revocation. While the app is still running, purchase the same product again and inspect the verified transaction returned directly by Product.purchase(). Both runtimes return .success with a verified transaction. On iOS 26.2, the repurchase returns a new transaction ID with revocationDate == nil, and Transaction.currentEntitlements contains it. On iOS 27.2, the result has the same ID, purchaseDate, and non-nil revocationDate as the refunded renewal. The current entitlement check yields no verified unrevoked transaction. This reproduced for both a monthly and a three-month subscription. The monthly case also reproduced when calling Product.purchase() without an appAccountToken option. Is this a known issue in StoreKit Testing on iOS 27.2 Simulator? Is there a supported way to test the repurchase path while preserving the refunded transaction in the test history?

StoreKit Testing on iOS 27.2 Simulator returns the refunded renewal when repurchasing a subscription
