Why is child theme’s style.css ignored?

I have made a child theme of the Idyllic theme by Freesia, following WordPress’s tutorial. The parent theme’s style.css is loaded and working fine. One can see that, because the page look just as with the Idyllic theme.

However, thy child’s theme style.css is ignored. I have tried to put all sorts of stylings there, adding important! but with no result. In the code inspector, none of these styles can be seen.

I have tried several version of functions.php file.

From this webpage:

function my_theme_enqueue_styles(){
  wp_enqueue_style("parent-style", get_parent_theme_file_uri("/style.css"));
}
add_action("wp_enqueue_scripts", "my_theme_enqueue_styles");
function my_theme_enqueue_styles() {
    wp_enqueue_style( 'parent_theme_style', get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child_theme_style', get_stylesheet_uri() );
}
add_action("wp_enqueue_scripts", "my_theme_enqueue_styles"); 

I have tried different things to put lower priority to the child theme’s style.css (from stackoverflow.com), so that it is loaded at the end…with no result:

function idyllicChild() {  
    // enqueue style
    wp_enqueue_style( 'parent', get_template_directory_uri().'/style.css' );    
}

function my_theme_enqueue_styles() {
    wp_enqueue_style( 'child-style', get_stylesheet_uri() );
}

add_action( 'wp_enqueue_scripts', 'idyllicChild');
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles', 11 );

But THEN I inspected closely what is actually getting loaded in the <head> of my page. The child style sheet is loaded twice. Why is that?

<link rel="stylesheet" id="idyllic-style-css" href="https://kalvarka.sk/wp-content/themes/idyllic-child/style.css?ver=61eb87ceb07e28a0e01ea94ef625322c" type="text/css" media="all">

And this file style.css is:

While the file style.css I am editing and is visible in ftp:

The parent style.css that is loaded https://kalvarka.sk/wp-content/themes/idyllic/style.css?ver=61eb87ceb07e28a0e01ea94ef625322c looks as expected (showing excerpt):

So the problem with child theme’s style.css is in the version

I have found a suggestion in stackoverflow.com. Actually, this WordPress’s official recommendation.

And BINGO!!! That was the problem. Now the child theme is loaded with the following:
