The issue has been brought up and supposedly Apple knows about it, but it has been about half a year without a response or fix: GKLocalPlayer.Local.FetchItems() Error on Unity - #5 by SebT_Unity
I am just wondering since Authentication is a paid service (of course there is a free tier), how this is acceptable?
Also, Social API is being depreciated. Is that plugin the new way to access leaderboards and achievements in iOS? If so, how long will it take for bugs to be fixed? It seems like we have to wait 6+ months so far. From what I have seen, its impossible to use that with macOS and iOS on any version of Unity I have tested (2022 and 2023)
Thanks!
