Getting blank screen running expo metro web Uncaught Error Related to RevenueCat

​@yavuzakyazici The react-native-purchases-ui package doesn’t support web, as we don’t (yet) have web paywalls. For web, you can use our web SDK for fetching customer info and making purchases, but paywalls aren’t yet supported.

I also get metatada warnings building expo eas locally. Is it related as well?

And also… If I put a flag for checking Platform, like below

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

Would I still get the error? 
I guess I would also need this flag everywhere I check for subscription and paywalls.
Actually, I should may be check platform before I create revenuecat functions?
Or even… do conditional imports.
Would that work?
