Hi John, thanks for the tipp! I tried to change from key to name but no difference. I also changed the name of the acf image to “bild” and adapted the code – but affects. I don’t understand why .. :/

//Auto assign Featured image from 'post_image'
function acf_set_featured_image( $value, $post_id, $field  ){

	$value = get_field('bild', $post_id);
    
    if($value != ''){
	    //Add the value which is the image ID to the _thumbnail_id meta data for the current post
	    update_post_meta($post_id, '_thumbnail_id', $value);
    }
    return $value;
}
add_filter('acf/update_value/key=bild', 'acf_set_featured_image', 10, 3);
