I'm using this screen to navigate between two screens by using the onAuthStateChanged but still every time It refresh the app it logs out even though I'm not log out.

import { View, Text, ActivityIndicator } from 'react-native'
import React, {useEffect } from 'react'
import { auth } from '../firebase';
import { useNavigation } from '@react-navigation/native';

const LoadingScreen = () => {
const navigation = useNavigation()
useEffect(() => {
    const unsubscribe = auth.onAuthStateChanged(user =>{
 if(user){
   navigation.replace('Chats') 
   //navigate to chat screen if user is exists
 }else{
   navigation.replace('Welcome') 
   //else navigate to first screen if no user
 }
 })
 return unsubscribe
 },[])
 return (
<View >
<ActivityIndicator size='large' />
</View>
 );
}

export default LoadingScreen
