we are selling only auto-renewable products.
Recently, several users has reported that they successfully purchased but not able to access content we provide.
By validate their encoded receipt, using apple api "https://buy.itunes.apple.com/verifyReceipt"
I got this
```
{
"receipt": {
"receipt_type": "Production",
"adam_id": someValue,
"app_item_id": someValue,
"bundle_id": someValue,
"application_version": "someValue",
"download_id": 9999,

"original_application_version": "someValue",
"in_app": []
},
"status": 0,
"environment": "Production"
}
```
And according to apples documentation:
```
In-App Purchase Receipt
The receipt for an in-app purchase.ASN.1 Field Type 17ASN.1 Field Value SET of in-app purchase receipt attributesJSON Field Name in_appJSON Field Value array of in-app purchase receiptsIn the JSON file, the value of this key is an array containing all in-app purchase receipts based on the in-app purchase transactions present in the input base-64 receipt-data. For receipts containing auto-renewable subscriptions, check the value of the latest_receipt_info key to get the status of the most recent renewal.In the ASN.1 file, there are multiple fields that all have type 17, each of which contains a single in-app purchase receipt.Note: An empty array is a valid receipt.
The in-app purchase receipt for a consumable product is added to the receipt when the purchase is made. It is kept in the receipt until your app finishes that transaction. After that point, it is removed from the receipt the next time the receipt is updated - for example, when the user makes another purchase or if your app explicitly refreshes the receipt.The in-app purchase receipt for a non-consumable product, auto-renewable subscription, non-renewing subscription, or free subscription remains in the receipt indefinitely.
```
So the question is,
If user has successfully purchased, and got an email confirmation from Apple,
WHY is "in_app" filed still empty array??
our service has been online for over a year and this seems to work fine until this week.
thanks
