Hi, just recently we have started receiving bug reports on an old game. In app purchases are not being properly credited / processed on iOS. The payment succeeds but the app is not reflecting the purchase properly. The app was last updated quite a while ago and has In App Purchasing plugin version 2.2.1 so I suspect this version is basically unsupported and perhaps a new change to the API has broken it. Is there a published list of supported versions and which versions are deprecated or planned to be deprecated?
The IAP package support follows the LTS schedule for Unity versions. Which means the current lowest version supported is: 2021.3 for Unity and IAP version 4.12.2.
