With some more research it seems I found a solution to this problem: in my functions.php of the child theme, I added:
function enqueue_child_theme_style() {wp_enqueue_style( ‘child-style’, get_stylesheet_directory_uri().’/style.css’ );}
add_action( ‘wp_enqueue_scripts’, ‘enqueue_child_theme_style’, 100 );
To enqueue the child theme style.css.
Maybe something to look into for other users?
