Hi everyone, I’m seeing a consistent one-day discrepancy between the expiresDate returned by the App Store Server API and the “Expires on” date shown in the iOS Settings / App Store subscription list. I’d like to confirm whether this behavior is expected or if I’m misunderstanding the way Apple rounds dates. Reproduction steps Step Action Result 1 Purchase a 1-month auto-renewable subscription on 23 June 2025 14:00 JST (UTC+9) Transaction succeeds 2 Immediately fetch the transaction with GET /inApps/v1/subscriptions/{transactionId} Response contains expiresDate: 2025-07-23T05:00:00Z (= 23 July 2025 14:00 JST) 3 On the same device open Settings › Apple ID › Subscriptions (or App Store › Account › Subscriptions) UI shows Expires on: 22 July 2025 The same happens for every monthly renewal and on multiple devices. Region is Japan, device time zone Asia/Tokyo. What I understand so far (and my hypothesis) Apple’s docs say a monthly subscription renews “on the same calendar date” of the next month, so renew
