I've recently integrated in-app purchases into a project. I work with React Native / Expo (EAS) and expo-in-app-purchases. They work great - however for most of them, the prices don't match the selected price tier in App Store Connect.
I have only consumable IAPs with the following price tiers (Germany):
As you can see, only the price of the first tier (Alternative Tier A) gets correctly reported by StoreKit. It's not only a display bug, too: When buying something in the Sandbox, it also shows the wrong pricing during the actual purchase process.
Has anyone experienced this in the past? What can I do?
After a little research, I've found some old posts in the Apple Developer forum saying this might be a sandbox bug. Even though I never found official confirmation of this, we've released our app to the App Store now. The prices are correct in the live version from the App Store. So this is indeed only a sandbox bug. The prices shown in App Store Connect will be the ones in the live app.
