ERROR: 🍎‼️ There was a problem with the App Store.

I’m getting a successful “response” from the native iOS purchase dialog (it gives me the check and the happy ding sound) but RevenueCat fails. Unfortunately, the failure also takes like 30 seconds to be responded to so beyond it failing, the failure is a bad UX and it’s not really clear how to handle it. Below are the debug logs. This is in our sandbox environment:
