Infinite Scroll appending Next Product Category Term pages

I'm using Infinite Scroll and the following great code from here to generate Next Taxonomy Term Link in a term loop. I want to ajax append Next Woocommerce Product Category when you reach the end of the current category.

Everything works fine except it only loads 1 term and then it says No more Items to show. Even the browser url changes depending on which term you are scroll positioned. Any idea if this is possible this way?

Next / Prev Terms links code:

    function get_tax_navigation( $taxonomy = 'category', $direction = '' ) 
{
    // Make sure we are on a taxonomy term/category/tag archive page, if not, bail
    if ( 'category' === $taxonomy ) {
        if ( !is_category() )
            return false;
    } elseif ( 'post_tag' === $taxonomy ) {
        if ( !is_tag() )
            return false;
    } else {
        if ( !is_tax( $taxonomy ) )
            return false;
    }

    // Make sure the taxonomy is valid and sanitize the taxonomy
    if (    'category' !== $taxonomy 
         || 'post_tag' !== $taxonomy
    ) {
        $taxonomy = filter_var( $taxonomy, FILTER_SANITIZE_STRING );
        if ( !$taxonomy )
            return false;

        if ( !taxonomy_exists( $taxonomy ) )
            return false;
    }

    // Get the current term object
    $current_term = get_term( $GLOBALS['wp_the_query']-get_queried_object() );

    // Get all the terms ordered by slug 
    $terms = get_terms( $taxonomy, ['orderby' = 'slug'] );

    // Make sure we have terms before we continue
    if ( !$terms ) 
        return false;

    // Because empty terms stuffs around with array keys, lets reset them
    $terms = array_values( $terms );

    // Lets get all the term id's from the array of term objects
    $term_ids = wp_list_pluck( $terms, 'term_id' );

    /**
     * We now need to locate the position of the current term amongs the $term_ids array. \
     * This way, we can now know which terms are adjacent to the current one
     */
    $current_term_position = array_search( $current_term-term_id, $term_ids );

    // Set default variables to hold the next and previous terms
    $previous_term = '';
    $next_term     = '';

    // Get the previous term
    if (    'previous' === $direction 
         || !$direction
    ) {
        if ( 0 === $current_term_position ) {
            $previous_term = $terms[intval( count( $term_ids ) - 1 )];
        } else {
            $previous_term = $terms[$current_term_position - 1];
        }
    }

    // Get the next term
    if (    'next' === $direction
         || !$direction
    ) {
        if ( intval( count( $term_ids ) - 1 ) === $current_term_position ) {
            $next_term = $terms[0];
        } else {
            $next_term = $terms[$current_term_position + 1];
        }
    }

    $link = [];
    // Build the links
    if ( $previous_term ) 
        $link[] = 'div class=tax-pages a class=prev href=' . esc_url( get_term_link( $previous_term ) ) . '' . $previous_term-name . '/a/div';

    if ( $next_term ) 
        $link[] = 'div class=tax-pages a class=next href=' . esc_url( get_term_link( $next_term ) ) . '' . $next_term-name . '/a/div';

    return implode( ' ...|... ', $link );
}

Infinite Scroll code

$('#main').infiniteScroll({
      path: .tax-pages a.next,
    hideNav: .tax-pages,
    append:  #main ul.products,
    status: '.page-load-status'
});
