Issue 1: Empty in_app array in receipt upon initial validation Description: Our server received the notification, but the receipt validation response returned an empty in_app array (in_app = []) on the initial check, preventing item delivery. Why did this receipt fail to include the transaction data initially? Issue 2: Missing Server Notifications and Transaction IDs Description: For the orders above, our server received no Server Notifications, and the client receipt callback lacked the transaction IDs, leading to missing deliveries. The issues mentioned above have resulted in some online users being unable to receive their goods despite having paid their bills.
