Standard newsletter form 404 after CAPTCHA

[alexmorris]

Working on a custom theme but want to use the standard newsletter signup. This seems to be fairly generically used across Shopify's own and other themes.

{% form 'customer' %}
  {{ form.errors | default_errors }}
  
    <input type="hidden" name="contact[tags]" value="newsletter">
    <div class="input-group">
      <input type="email" value="" placeholder="" name="contact[email]" id="NewsletterEmail"  autocorrect="off" autocapitalize="off">
      <div class="input-group__btn">
        <button type="submit" class="btn" name="commit" id="Subscribe">go</button>
      </div>
    </div>
  
{% endform %}

However, if you try to add an email address, CAPTCHA appears with a second submit button which then attempts to hit /contact which 404's - and the email is not captured in the customer list.
