- Unity IAP stops receiving callbacks on our IStoreListener implementation
Unity IAP’s StandardPurchasingModule relies upon a persistent GameObject named “IAPUtil”. This hidden, “DontDestroyOnLoad”-configured object can be destroyed by a game script which cleans GameObjects from the scene hierarchy (potentially useful for scene transitions). This results in Unity IAP no longer working as expected.
To fix, add an exception in the app’s hierarchy cleanup script for the “IAPUtil” GameObject.
