RevenueCatUI/DebugErrorView.swift:68: Fatal error: Purchases has not been configured

Hello everyone,

I got RevenueCat working with Expo iOS development build but when I submit to appstore or even do a local preview build, app crashes on startup.

I connected my iPhone to my mac with cable and launched the console app. And when I filtered the streaming console I found this error that caused the crash 

RevenueCatUI/DebugErrorView.swift:68: Fatal error: Purchases has not been configured.

However, I did configure the Purchases at the very root in my App.js
I tried these both…
 

  const configurePurchases = async () => {
    if (Platform.OS === "ios") {
      Purchases.configure({ apiKey: process.env.EXPO_PUBLIC_RC_IOS });
    }
  };

  configurePurchases();

and… 

 

const configurePurchases = async () => {
    if (Platform.OS === "ios") {
      Purchases.configure({ apiKey: process.env.EXPO_PUBLIC_RC_IOS });
    }
  };
  useEffect(() => {
    async function init() {
      await configurePurchases();
    }
    init();
  }, []);

They both work at the development build on a physical device.
But they both crash at startup on TestFlight or local Preview Build.

And when it crashes Mac Console App says..
“RevenueCatUI/DebugErrorView.swift:68: Fatal error: Purchases has not been configured.”

It was working fine before. I don’t know what happened or how to fix this.
Can anybody help?
