[Divi Coming Soon Snippet]Divi allows you to create coming soon pages (blank template), but when someone tries to reach something like "my-domain.com/about/", it will achieve it because there is no implementation to hide those pages.This is what this simple snippet can do for you.

coming-soon-snippet.php

<?php
// Create a page called "Coming Soon"
// Make sure that the permalink looks like this: my-domain.com/coming-soon/
// Then paste the snippet below into your themes (child-themes) functions.php.
// After inserting, any user who is not logged-in will be redirected to your coming-soon page.

add_action( 'init', function()
{

    if( ! is_user_logged_in() )
    {

        if ( isset( $_SERVER['REQUEST_URI'] )
            && ( '/coming-soon/' == $_SERVER['REQUEST_URI']
                || '/wp-admin/' == $_SERVER['REQUEST_URI']
                || false !== strpos( $_SERVER['REQUEST_URI'], 'wp-login.php' ) ) ) return;

        wp_redirect( '/coming-soon/' );

        exit;

    }

});
