ProcessPurchase not called on startup (Android)
Hi, I'm trying to get the Unity IAP system working on Android. Almost everything seems to work. But when I restart my app, the ProcessPurchase method is not called. Therefore the purchased items are not unlocked in-game. From what I can read in the documentation (https://docs.unity3d.com/Manual/UnityIAPRestoringTransactions.html), this method should be called automatically.
The logcat output indicates the items are marked as 'owned'. But because the transaction is already recorded, it isn't processed again? How do I get Unity to call ProcessPurchase for these purchases?
EDIT: Okay, I just found out that it does work the first time the app starts after installing it. So it seems Unity assumes you locally keep track of what should be unlocked with the user's purchases? This seems more prone to users gaining content by modifying local data.
