Describe the bug

Login process takes an excessive amount of time (15 - 30 seconds) and causes the interface to freeze

Expected behavior

The login process should be swift, typically completing within a few seconds. Additionally, the user interface should remain responsive at all times

Reproduction steps

1. Create an Expo application.
2. Configure Amplify.
3. Launch the application using expo go app.

Code Snippet

// Put your code below this line.
import { StatusBar } from 'expo-status-bar';
import { StyleSheet, Text, View, Button } from 'react-native';
import { Amplify, Auth } from "aws-amplify";
import awsConfig from "./src/aws-exports";

Amplify.configure(awsConfig);
Amplify.Logger.LOG_LEVEL = "VERBOSE"


export default function App() {

  async function onSignInPressed() {
    console.log("onSignInPressed", new Date());

    await Auth.signIn("someLogin", "somePassword");

    console.log("onSignInPressed end", new Date());
  }

  return (
    <View style={styles.container}>

      <Button title="Sign In" onPress={() => onSignInPressed()} />

      <StatusBar style="auto" />
    </View>
  );
