I am seeing the exact same problem and yes, our tests also show this only happening on 18.4.1 Not sure what the fix here is. Have created a report with Apple for code level support. This issue has currently blocked us from a production rollout

hi @MikaHoff , did you find a solution for this? In my case I noticed that if I use a difference "team" then I don't get this error and sign in works as expected but if I use my org team it stops working (which was working til day before). This behavior is the same even when trying sample app from apple https://developer.apple.com/documentation/sign_in_with_apple/implementing_user_authentication_with_sign_in_with_apple ie not working with org team but working with individual developer account

I have the exact same problem, it was working fine till yesterday but suddenly broke without any changes in the app or the backend

Hello again, Is there any update on this? The behavior in recent tests is the same - I am receiving a CONSUMPTION_REQUEST notification but no REFUND notification

Hello, I have filed a ticket in Feedback Assistant: FB13479944 It has the JWSTransactionDecodedPayload that I received with the NotificationTypeV2.CONSUMPTION_REQUEST Thanks
