By default WooCommerce redirects the user to the My Account page after a successful login. You may change this and use a custom URL based on the user role, like the Dashboard for admins and My Account page for customers. To do this, add this code at the end of the file functions.php located in wp-content/themes/your-theme-name/ https://support.w…
<?php
/**
* Redirect users to custom URL based on their role after login
*
* @param string $redirect
* @param object $user
* @return string
*/
function wc_custom_user_redirect( $redirect, $user ) {
// Get the first of all the roles assigned to the user
