count_user_posts on multisite network

Hi,
I’m trying to use count_user_posts to get the number of posts a user has edited on different subsites and in different post types. That’s why I use switch_to_blog.
I then want to display this count through a shortcode on the user’s profile, which is managed by ultimate member.

My problem is the following code works only if the post type is page or post, but I need it to work with CPTs (woocommerce products on site 4 and activities on site 1).

I hope you’ll be able to help me because I can’t get what’s wrong … Thank you so much in advance, here’s the code :

function afficher_nb_posts_user() {

	global $ultimatemember;
	$quest_user = um_profile_id();

    		switch_to_blog(4);
		$myquest_post_count = count_user_posts( $quest_user , 'product' );
    		restore_current_blog();

    		switch_to_blog(1);
		$quest_post_count = count_user_posts( $quest_user , 'page' );
    		restore_current_blog();

	$total_posts = ($myquest_post_count + $quest_post_count);
	return $total_posts;
}
add_shortcode( 'nb_posts_user', 'afficher_nb_posts_user' );
