react context-api conditional-rendering JavaScript

I need some guidance on I'm not sure how to approach I can't seem to get I'm facing an issue with conditional rendering in my React application using the Context API... I have a context that manages user authentication and based on the authentication state, I want to render different components. However, I'm observing that the components do not update as expected when the authentication state changes. Here's a simplified version of my context provider: ```javascript import React, { createContext, useState, useContext } from 'react'; const AuthContext = createContext(); export const AuthProvider = ({ children }) => { const [isAuthenticated, setIsAuthenticated] = useState(false); const login = () => setIsAuthenticated(true); const logout = () => setIsAuthenticated(false); return ( <AuthContext.Provider value={{ isAuthenticated, login, logout }}> {children} </AuthContext.Provider> ); }; export const useAuth = () => useContext(AuthContext); ``` In my main component, I have: ```javascript import React from 'react'; import { AuthProvider, useAuth } from './AuthContext'; const AuthenticatedComponent = () => <div>Welcome back!</div>; const UnauthenticatedComponent = () => <button onClick={login}>Login</button>; const App = () => { const { isAuthenticated } = useAuth(); return ( <div> {isAuthenticated ? <AuthenticatedComponent /> : <UnauthenticatedComponent />} </div> ); }; const Root = () => ( <AuthProvider> <App /> </AuthProvider> ); export default Root; ``` When I call the `login` function from the `UnauthenticatedComponent`, it updates the state in the context but the UI doesn't reflect this change. I have tried adding `console.log` statements in both the `login` function and the `App` component to verify that the state is indeed changing, and it is, but the UI remains stale. I also checked if the components are wrapped correctly with the context provider, and they are. The React version I’m using is 17.0.2. Could this be a problem related to how state updates propagate in function components, or is there something I'm missing with the Context API? Any insights would be greatly appreciated. I recently upgraded to Javascript latest. Any suggestions would be helpful. I've been using Javascript for about a year now. I'm open to any suggestions.
