Question:
I'm encountering an issue with in-app purchases (IAP) in Unity, specifically for a non-consumable product in the iOS sandbox environment. Below are the details:
Environment:
Unity Version: 2022.3.55f1 Unity In-App Purchasing Version: v4.12.2 Device: iPhone (15, iOS 18.1.1) Connection: Wi-Fi iOS Settings: In-App Purchases set to “Allowed” initially Problem Behavior:
-
I attempted to purchase a non-consumable item for the first time. The payment is successfully completed by entering the password.
-
I then background the game app and navigate to the iOS Settings to set In-App Purchases to "Don't Allow."
-
After returning to the game and either closing or killing the app, I try to purchase the same non-consumable item again.
-
I checked canMakePayments() through the Apple configuration, and the app correctly detected that I could not make purchases due to the restriction.
-
I then navigate back to Settings and set In-App Purchases to "Allow."
-
Upon returning to the game, I try purchasing the non-consumable item again. A pop-up appears, saying, "You’ve already purchased this. Would you like to get it again for free?"
The issue is: Will it deduct money for the second time, and why is the system allowing the user to purchase the same non-consumable item multiple times after purchasing it once?
Is this the expected behavior for Unity In-App Purchasing, or is there something I might be missing in handling non-consumable purchases in this scenario?
Additional Information:
I’ve confirmed that the "In-App Purchases" are set to “Allowed” before attempting the purchase again.
I understand that non-consumable products should not be purchased more than once, so I’m unsure why the system is offering to let the user purchase it again.
I appreciate any insights into whether this is expected behavior or if I need to adjust how I handle the purchase flow.
