I solved it by adapting John’s code. Thank you.
<?php while ( have_posts() ) : the_post(); ?>
<?php
if (is_user_logged_in() && current_user_can('cliente')) {
// Get the current user
$current_user_id = get_current_user_id();
$args = array(
'post_type' => 'clientes',
'author' => $current_user_id
);
$posts = get_posts($args);
if ($posts) {
$post_id = $posts[0]->ID;
}
acf_form(array(
'post_id' => $post_id,
'submit_value' => __('Actualizar Mi perfil'),
));
}
?>
<?php endwhile; ?>
