Guys here is the working code snippet for Display coupon usage count and limit in WooCommerce thank you page and please use carefully:

1. Guys here is the code snippet and you need to add your theme’s functions.php file

function woo_add_multiple_products_to_cart( $url = false ) {
  // Make sure WC is installed, and add-to-cart qauery arg exists, and contains at least one comma.
  if ( ! class_exists( 'WC_Form_Handler' ) || empty( $_REQUEST['add-to-cart'] ) || false === strpos( $_REQUEST['add-to-cart'], ',' ) ) {
    return;
  }

  // Remove WooCommerce's hook, as it's useless (doesn't handle multiple products).
  remove_action( 'wp_loaded', array( 'WC_Form_Handler', 'add_to_cart_action' ), 20 );

  $product_ids = explode( ',', $_REQUEST['add-to-cart'] );
  $count       = count( $product_ids );
  $number      = 0;

  foreach ( $product_ids as $id_and_quantity ) {
    // Check for quantities defined in curie notation (<product_id>:<product_quantity>)
    
    $id_and_quantity = explode( ':', $id_and_quantity );
    $product_id = $id_and_quantity[0];

    $_REQUEST['quantity'] = ! empty( $id_and_quantity[1] ) ? absint( $id_and_quantity[1] ) : 1;

    if ( ++$number === $count ) {
      // Ok, final item, let's send it back to woocommerce's add_to_cart_action method for handling.
      $_REQUEST['add-to-cart'] = $product_id;

      return WC_Form_Handler::add_to_cart_action( $url );
    }

    $product_id        = apply_filters( 'woocommerce_add_to_cart_product_id', absint( $product_id ) );
    $was_added_to_cart = false;
    $adding_to_cart    = wc_get_product( $product_id );

    if ( ! $adding_to_cart ) {
      continue;
    }

    $add_to_cart_handler = apply_filters( 'woocommerce_add_to_cart_handler', $adding_to_cart->get_type(), $adding_to_cart );

    // Variable product handling
    if ( 'variable' === $add_to_cart_handler ) {
      woo_hack_invoke_private_method( 'WC_Form_Handler', 'add_to_cart_handler_variable', $product_id );

    // Grouped Products
    } elseif ( 'grouped' === $add_to_cart_handler ) {
      woo_hack_invoke_private_method( 'WC_Form_Handler', 'add_to_cart_handler_grouped', $product_id );

    // Custom Handler
    } elseif ( has_action( 'woocommerce_add_to_cart_handler_' . $add_to_cart_handler ) ){
      do_action( 'woocommerce_add_to_cart_handler_' . $add_to_cart_handler, $url );

    // Simple Products
    } else {
      woo_hack_invoke_private_method( 'WC_Form_Handler', 'add_to_cart_handler_simple', $product_id );
    }
  }
}

// Fire before the WC_Form_Handler::add_to_cart_action callback.
add_action( 'wp_loaded', 'woo_add_multiple_products_to_cart', 15 );


/**
 * Invoke class private method
 *
 * @since   0.1.0
 *
 * @param   string $class_name
 * @param   string $methodName
 *
 * @return  mixed
 */
function woo_hack_invoke_private_method( $class_name, $methodName ) {
  if ( version_compare( phpversion(), '5.3', '<' ) ) {
    throw new Exception( 'PHP version does not support ReflectionClass::setAccessible()', __LINE__ );
  }

  $args = func_get_args();
  unset( $args[0], $args[1] );
  $reflection = new ReflectionClass( $class_name );
  $method = $reflection->getMethod( $methodName );
  $method->setAccessible( true );

  //$args = array_merge( array( $class_name ), $args );
  $args = array_merge( array( $reflection ), $args );
  return call_user_func_array( array( $method, 'invoke' ), $args );
}
