Redirect Logged-In Users to Their Full Level User Page from the Top Level Parent Page

my-pmproup-redirect-top-level-to-user-page.php

<?php
/**
 * Redirect logged-in members visiting /top-level-page/ to their full user level page. Works best for single level setup.
 * (e.g., /top-level-parent-page/username/user-page/) immediately, skipping the intermediate user page.
 *
 * This improves UX by automatically taking users to their specific level user page
 * without requiring a second click.
 *
 * This recipe assumes the User Pages Add On is installed and configured.

 *
 * You can add this recipe to your site by creating a custom plugin
 * or using the Code Snippets plugin available for free in the WordPress repository.
