Hello. It seems that some customers are having a problem receiving Push notifications sent by our app. There is only one transmission history on the server. Some users receive only one notification, while others receive multiple notifications. There are no in-app notifications, and all notifications are sent from the server. Given this situation, we believe that there may be a problem on the OS side that receives the push notifications. We would appreciate any solutions or information you can provide. As an example, we will send you information on the actual push notification where the duplication occurred. This is occurring on iOS16 as well as iOS17. Thank you. regards. === Payload: { "aps": { "alert": { "title": "", "body": "{body}" } }, "nd_custom": { "tap_location_url": "{url}", } "send_no": "861917" }, } "show": "1" } Date and time of transmission: Nov 10, 2023 23:00:03 ===

When verifying the receipt, in the "pending_renewal_info" block, "is_in_billing_retry_period" may be 0, but "expiration_intent" may not exist. What does this situation represent? Is it okay to decide that this purchase is invalid? Thank you.
