ValidateIOSReceipt doesn't work in production.
In sandbox it works as expected but once it is a real purchase from the appstore it starts to return ServiceUnavailable (1123) error.
I tried to catch any info from the PlayStream by making a purchase by myself but the ValidateIOSReceipt is not registered and it doesn't show up when it throws a 1123.
So I can't post any additional information.
By the way, I'm using Unity 2022.1.
Any ideas? I had to stop in-app purchases because of that.
