I’ve been integrating the Appstore SDK Plugin for Unity (v3.0.2) into a Unity app and testing it using the Live App Testing service. All of the IAP methods and responses are working as expected except for retrieving purchase transactions using GetPurchaseUpdates.
I’m trying to use GetPurchaseUpdates(true) to retrieve the entire transaction history so that I can check whether the user has an active subscription for any given subscription IAP. Calling GetPurchaseUpdates(true) is retrieving transactions as expected for consumable and entitlement IAPs, however, only some transactions are being retrieved for subscription IAPs. Notably, the transaction for any active subscription is always missing from the retrieved GetPurchaseUpdatesResponse object. The retrieved GetPurchaseUpdatesResponse object’s hasMore field is false so it doesn’t seem to be a result of missing transactions due to pagination.
As far as I can tell I’m following the purchasing flow correctly for the subscriptions - I’m getting email receipts for the purchases and the subscriptions are showing in my account’s active subscriptions - so I’m not sure why the transactions aren’t being retrieved successfully. It’s my understanding that GetPurchaseUpdates(true) should be retrieving a full transaction history. Any help with this would be greatly appreciated.
Here is the code that I’m using:
