In app purchase

Greetings community members,

I am currently navigating the intricacies of in-app purchases in my React Native application. Specifically, I am in the process of integrating auto-renewable subscriptions using the 'react-native-iap' package. Below is the complete code snippet I have implemented. While I have successfully fetched the subscriptions, I encounter an issue during the subscription process. After triggering the sandbox UI, a subscribe button appears. However, upon selecting it, a sign-in prompt is presented. Despite providing the correct credentials, the intended action does not occur.

I would greatly appreciate any insights or guidance on resolving this matter. Thank you in advance for your assistance.

import { View, Text, Button, StyleSheet, Alert, Platform } from 'react-native'; // Import Platform
import {
  useIAP,
  validateReceiptIos,
  finishTransaction,
} from 'react-native-iap';
import axios from 'axios';
import { ITUNES_SHARED_SECRET } from "@env";

const SubscriptionScreen = ({ navigation }) => {
  const {
    requestSubscription,
    getSubscriptions,
    currentPurchase,
    purchaseHistory,
  } = useIAP();
  const [subscriptionStatus, setSubscriptionStatus] = useState(false);
  const [loading, setLoading] = useState(false);

  useEffect(() => {
    handleGetSubscriptions();
  }, []);

  useEffect(() => {
    if (purchaseHistory && purchaseHistory.length > 0) {
      const isSubscribed = purchaseHistory.some((purchase) =>
        subscriptionSkus.includes(purchase.productId)
      );

      if (isSubscribed) {
        setSubscriptionStatus(true);
      }
    }
  }, [purchaseHistory]);

  const subscriptionSkus = Platform.select({
    ios: ['sub1', 'sub2', 'sub3'],
  });

  const handleGetSubscriptions = async () => {
    try {
      await getSubscriptions({ skus: subscriptionSkus });
    } catch (error) {
      console.error('Error getting subscriptions:', error);
    }
  };

  const handleBuySubscription = async (productId) => {
    try {
      setLoading(true);

      // Request subscription
      const purchase = await requestSubscription({
        sku: productId,
        ...(Platform.OS === 'ios' && { andDangerouslyFinishTransactionAutomaticallyIOS: false }), // Handle differently for iOS
      });

      // Finish the transaction
      await finishTransaction({
        purchase,
        isConsumable: false,
      });

      // Check if the purchase was successful
      if (purchase.transactionState === 'Purchased') {
        // Validate the receipt
        const receipt = purchase.transactionReceipt;
        await handleValidateReceipt(receipt);

        // Navigate to the desired screen
        navigation.navigate('IndexPage');
      } else {
        // Handle other transaction states if needed
        console.warn('Transaction state:', purchase.transactionState);
      }
    } catch (err) {
      console.error(err.code, err.message);
    } finally {
      setLoading(false);
    }
  };

  const handleValidateReceipt = async (receipt) => {
    try {
      const isTestEnvironment = false;
      const response = await validateReceiptIos(
        {
          'receipt-data': receipt,
          password: ITUNES_SHARED_SECRET,
        },
        isTestEnvironment
      );

      if (response && response.status === 0) {
        // Receipt is valid, you may want to save the purchase on your server
        const serverValidationResult = await validateReceiptOnServer(receipt);
        if (serverValidationResult.valid) {
          setSubscriptionStatus(true);
          Alert.alert('Subscription Purchased', 'Thank you for subscribing!');
        } else {

        }

      }
    } catch (error) {
      console.error('Error during receipt validation:', error);
    }
  };

  const validateReceiptOnServer = async (receipt) => {
    try {
      // Replace with your server endpoint for receipt validation
      const response = await axios.post('', { receipt });
      return response.data;
    } catch (error) {
      console.error('Error validating receipt on server:', error);
      return { valid: false };
    }

        <Button
          key={sku}
          title={`Purchase ${sku}`}
          onPress={() => handleBuySubscription(sku)}

export default SubscriptionScreen;```
