Hello, We are currently testing subscription purchases in the Sandbox environment, and we are seeing an issue that we do not fully understand. When we attempt a single subscription purchase, multiple purchase signals or transaction events are sometimes delivered from Sandbox for what appears to be just one payment attempt. In some cases this happens twice, and in other cases we have seen it occur as many as five to seven times. The number is inconsistent each time, and we have not been able to identify any clear pattern. At this point, we are not sure whether this is a known instability or limitation of the Sandbox testing environment, or whether there may be something incorrect in our own implementation or configuration. Has anyone experienced similar behavior when testing auto-renewable subscriptions in Sandbox? If so, we would really appreciate any guidance on what to check. Thank you.

Hello, I have a question regarding how prorated refunds are reflected when a user upgrades a subscription. From my understanding, when a user upgrades to a higher-tier subscription, the remaining value of the current subscription is refunded as a prorated amount, typically represented as REFUND_PRORATED or PRORATED_CREDIT. However, when reviewing the available transaction history and refund-related data (including the App Store Server API and transaction history endpoints), I cannot find any field or record that clearly indicates: the actual prorated refund amount, or the credit applied when upgrading to another subscription In other words, while the concept of REFUND_PRORATED seems to exist conceptually, I cannot identify where the actual prorated value or credit applied to the upgrade is exposed in the transaction or refund history. My questions are: Is there any way to retrieve the actual prorated refund or credit amount when a user upgrades a subscription? Is this information available through the App Store Server API (e.g., Get Transaction History) or any other API endpoint? If not, is there any recommended method to determine how much of the previous subscription was credited toward the upgraded subscription? Any clarification would be greatly appreciated. Thank you for your help.

Hello, I am currently testing In-App Purchases for my app in the Sandbox environment. Our app has two types of products: Auto-renewable subscriptions Non-renewing subscriptions When testing auto-renewable subscriptions, I can see the subscription in the Sandbox account management screen, and I can perform actions such as: Viewing the active subscription Cancelling the subscription Upgrading or downgrading the subscription However, when testing non-renewing subscriptions, I cannot find the purchase history anywhere in the Sandbox account management screen. Because of this, I cannot verify whether the non-renewing subscription purchase was recorded correctly. My question is: Where can I check the purchase history for Non-Renewing Subscriptions in the Sandbox environment? Is there a specific place in: App Store Connect Sandbox account settings Or somewhere else where these purchases can be reviewed? Thank you in advance for your help.
