/**
 * Email verification page.
 *
 * This displays instead of the thankyou page any time that the customer cannot be identified.
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/checkout/thankyou-verify-email.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you (the theme developer) will need to copy
 * the new files to your theme to maintain compatibility. We try to do this as little as possible, but it does happen.
 * When this occurs the version of the template file will be bumped and the readme will list any important changes.
 *
 * @see     https://woocommerce.com/document/template-structure/
 * @package WooCommerce\Templates
 * @version 7.9.0
 *
 * @var bool   $failed_submission Indicates if the last attempt to verify failed.
 * @var string $verify_url        The URL for the email verification form.
