Sudden IOS purchases broken

What Unity Version?

I’m on 2022.3.3.1f and works fine for me.

The reason you needed to update:

Important update: Support for in-app receipt validation for SHA-256 Apple Receipts.

The In-App Purchasing SDK version 4.9.4 now uses the SHA-256 algorithm to decode Apple receipts for those using the CrossPlatformValidator. Apple is changing its receipt format on August 14th: Upcoming changes to the App Store receipt signing intermediate certificate - Latest News - Apple Developer. Please update to IAP 4.9.4 in your package manager if your app is using this feature. Older receipts encoded in SHA-1 are still supported.
