We try to get notification history records with endpoint below: https://developer.apple.com/documentation/appstoreserverapi/get_notification_history but it returns no data , example of return: {"notificationHistory":[],"hasMore":false} our app still using the server notification V1, It it we can't get data from the api as long as we don't upgrade to v2？ please help， thanks

doc: https://developer.apple.com/documentation/appstoreserverapi/get_refund_history api doc tell me that "the API returns the complete list of the customer’s refunds for your app. " but in my case, we find that this api only return the leatest 50 refund transaction for us, how can we get the earlier refund transaction ？ please help！

In apple’s document： https://developer.apple.com/documentation/storekit/original_api_for_in-app_purchase/handling_refund_notifications memtion in document： Your server is responsible to parse and interpret all notifications from App Store Server. For the REFUND notification, identify the specific transaction, product ID, and relevant dates from the response: Find the most-recent transaction for the product_id in the unified_receipt.latest_receipt_info by checking the purchase_date to select the most-recent transaction. The date when App Store issued the refund is in the cancellation_date_ms field for this transaction. My problem is that , we find that unified_receipt.latest_receipt_info is an array, It contains multiple trasactions and these t'rascations all have ”cancellation_date_ms“ field . I would like to know if I should process all the trasactions have field ”cancellation_date_ms“ or just the latest one？ please help！！
