Trash realated post by custom field value in multisite - multisite

Question

I have a multisite setup were the custom post type article has a relation to other posts at the network by the custom field alphanumeric_id This key is unique on each blog and the related posts are generated programmatically on add_action('wp_insert_post', 'bZive_create_TranslatedContent', 15, 3);
function bZive_trash_TranslatedContent($post_id){
// Get the current blog id
$original_site_id = get_current_blog_id();
$postTypes = array('profile', 'article');
$postType = get_post_type( get_the_ID() );
$randomString = get_post_meta( get_the_ID(), 'alphanumeric_id', true );
$args = array(
'public' => true,
'limit' => 500
);
$sites = wp_get_sites($args);
$tests = array();
foreach ($sites as $site) {
switch_to_blog($site['blog_id']);
if( get_current_blog_id() != $original_site_id and get_current_blog_id() != 1 ){
$args = array(
'post_type' => 'article',
'post_status' => array(
'publish', 'draft', 'pending','auto-draft', 'future', 'private'
),
'meta_query' => array(
array(
'key' => 'alphanumeric_id',
'value' => $randomString ,
'compare' => '=',
),
),
);
$posts = new WP_Query($args);
if( $posts->have_posts() ) {
while( $posts->have_posts() ) {
$posts->the_post();
// Move the post to trash
wp_trash_post(get_the_ID());
}
}
wp_reset_postdata();
}
restore_current_blog();
}
}
add_action('trash_post','bZive_trash_TranslatedContent',10,3);
What I want to archive: If I move one post to the trash - all related post should be moved to the trash too. But somehow the posts aren't getting deleted - I tested the WP_Query it's getting the right posts but still, they don't get deleted.

Finally working!
function bZive_trash_TranslatedContent($post_id){
// Get the current blog id
$original_site_id = get_current_blog_id();
$postTypes = array('profile', 'article');
$postType = get_post_type( get_the_ID() );
$randomString = get_post_meta( get_the_ID(), 'alphanumeric_id', true );
if (in_array( $postType, $postTypes ) and empty( get_post_meta( $post_id, 'del_translatedContent', true ) ) ) {
add_post_meta($post_id, 'del_translatedContent', 'true');
$args = array(
'public' => true,
'limit' => 500
);
$sites = wp_get_sites($args);
$tests = array();
foreach ($sites as $site) {
