Empty list in products

Hello, 

I am using React-native and building an app in IOS. It is strange that when i try to use this function, it returns me nothing. when i try to get offerings, it returns me an an error that There is an issue with your configuration. Check the underlying error for more details. There's a problem with your configuration. None of the products registered in the RevenueCat dashboard could be fetched from App Store Connect

```

useEffect(() => {

    async function fetchOfferings() {

         await Purchases.setLogLevel('info');

        await Purchases.configure({apiKey:<API_KEY>});

        const products = await Purchases.getOfferings(['promonthly']);

console.log(products)

}

fetchOfferings();

}, []);

``` 

I have also tried every single suggestions in 

Nothing seems to work. I tried using my phone and then the simulator and both returns empty. Any help is greatly appreciated.
