I'm accessing the receipt after a successful in-app subscription (by checking SKPaymentTransactionStatePurchased state). After I verified this receipt, in the receipt verification response "expiration_date", "expiration_date_ms", and "expiration_date_pst" are are missing under "receipt". Why is that?
(As a workaround I tried to get the last object of latest_receipt_info and refer its expiration date. But this data is referring to the last subscription before the current one. So I cannot find the required expiration date there.)
How can I resolve this and retrieve the expiration date of the subscription purchased just now?
