Custom Post Type Query in Shortcode Gives No Results

I’m using a code that I’ve had no problems with on normal WP installations to query a custom post type. The function is displayed on the site using a shortcode that returns the results of the query. I’ve attempted to use this same code on a site set up on a multisite network and can’t get any results.

I’ve even tried using switch_to_blog() and restore_current_blog() within the function but have had no luck in getting my query to show any results.

Below is the code I’m currently using. I’ve commented out the tax_query for now while debugging it.

function create_chalk_holders_list( $atts, $content = null ) {

    switch_to_blog(2);

	$string = '<div class="products-wrapper chalk-holders">';

	$tax = array(
		array(
            'taxonomy' => 'productcollection',
            'field' => 'slug',
            'terms' => 'chalk'
        )
	);

	$args = array(
        'post_type' => 'products',
        //'tax_query' => $tax,
        'meta_key' => 'number',
        'orderby' => 'meta_value',
        'order' => 'ASC',
        'showposts' => 100
    );

    $the_query = new WP_Query ( $args );

    if ( $the_query->have_posts() ) {
    	while ( $the_query->have_posts() ) {
    		$the_query->the_post();

    		// Output for each product
            // Deleted to simplify post
    	}
    } else {
    	// nothing to display
        $string .= get_current_blog_id();
    }

    wp_reset_postdata();

    $string .= '</div><!-- .products-wrapper .chalk-holders -->';

    return $string;

    restore_current_blog();

}

add_shortcode( 'show_chalk_holders', 'create_chalk_holders_list' );
