Question Sudden IOS purchases broken

All of a sudden after app update, all IOS purchases are failing verification client side.
Sandbox purchase works, real purchase fail.

There HAS NOT been any changes made to IAP code.

Any ideas anyone?

 

We encounter the same issue and update to 4.9.4 solved it.

check the changelog below
https://docs.unity3d.com/Packages/com.unity.purchasing@4.9/changelog/CHANGELOG.html

 

But IAP package and code didn't get updated, why would the certificate chain suddenly change?

If it did change, why would sandbox work?
Did your sandbox purchase work before updating to 4.9.4?

 

It works on our sandbox too, and it fail on live production environment. We being forced to test it on actual server AFTER update to 4.9.4 to validate this fix

 

Thanks, will try 4.9.4.

 

This is so terrible.

Have to release the app to test "REAL" purchase.

If it is in fact IAP Lib issue, Unity really have major problems with regards to this.

 

What Unity Version?

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

The reason you needed to update:

I updated the In App Purchasing package to 4.9.4 but I'm still experiencing the issue. The IAP works on testflight but doesn't work on the store released version. Is anyone experiencing the same behavior on 4.9.4?
