child theme not working

Hello,

I apologize for this stupid question but I’m stuck with a basic child theme question.
I have done everything described in wordpress developer’s documentation but even if the child style.css is loaded on my website the change I have made in my child style.css doesn’t override the chaplin style.css.

The chaplin style.css is the one used first even if I modify child css.

Child style.css

/*
	Theme Name: Chaplin Child
	Description: Chaplin child 
	Template: chaplin
	Version: 1.1.2
*/

a {
	color: #007C89;
	text-decoration: none;
}

function.php as described in the documentation (tried both options)

<?php
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
 
    $parent_style = 'parent-style'; // This is 'twentyfifteen-style' for the Twenty Fifteen theme.
 
    wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child-style',
        get_stylesheet_directory_uri() . '/style.css',
        array( $parent_style ),
        wp_get_theme()->get('Version')
    );
}

It’s works fine with other theme. (I replaced chaplin by twentytwenty in style.css of my child theme and it works.

Sorry about that, but if somebody have any clue…

Thanks
