Hi there!
I don’t know if I can support you, but have you tried something like this in your functions.php?
<?php
/* enqueue script for parent theme stylesheeet */
function childtheme_parent_styles() {
// enqueue style
wp_enqueue_style( 'parent', get_template_directory_uri().'/style.css' );
}
add_action( 'wp_enqueue_scripts', 'childtheme_parent_styles');
I had the same problem like you and with me this worked 🙂
