Hi,

Verify Metafield Setup
At Product Template - insert code to display cross-sell product

Code example

{% assign cross_sell_product_id = product.metafields.namespace.key %}

{% if cross_sell_product_id %}
  {% assign cross_sell_product = all_products[cross_sell_product_id] %}

  {% if cross_sell_product %}
    <div class="cross-sell">
      <h3>Recommended for you</h3>
      <a href="{{ cross_sell_product.url }}">
        <img src="{{ cross_sell_product.featured_image | img_url: 'medium' }}" alt="{{ cross_sell_product.title }}">
        <p>{{ cross_sell_product.title }}</p>
      </a>
    </div>
  {% endif %}
{% endif %}
