Since February 1, Reserved Metafield Values Set by Other Apps Are No Longer Retrieved from Theme App Extension Liquid Files

Hello,

As mentioned in the title, metafield values that were successfully retrieved until January 31 have suddenly stopped being retrieved at some point after February 1.

I am using the following code in my theme extension:

<div id="{{ block.id }}">
  <h2 class="ebooks__title">Ebooks</h2>
  <div class="ebooks">
    {% for order in customer.orders %}
      {% for line_item in order.line_items %}
        {% if line_item.product.metafields['app--1234567--hogehoge'].content_id != null %}
          <div class="line-item">
            <div class="line-item__thumbnail">{{ line_item | image_url: height: 120 | image_tag }}</div>
            <div class="line-item__wrapper">
              <p class="line-item__title">{{ line_item.title }}</p>
              <div class="line-item__menu">
                <div class="line-item__button">
                  <a href="/apps/hogehoge/products/{{ line_item.product.id }}" class="button">View</a>
                </div>
                <p class="line-item__date">Order Date:{{ order.created_at | date: format: 'abbreviated_date' }}</p>
              </div>
            </div>
          </div>
        {% endif %}
      {% endfor %}
    {% endfor %}
  </div>
</div>

{% schema %}
{
  "name": "Ebooks",
  "target": "section",
  "stylesheet": "ebooks.css",
  "javascript": "ebooks.js",
  "templates": ["index", "customers/account", "customers/order"],
  "settings": []
}
{% endschema %}

This extension, which is added to the order history page, is intended to display only those orders that have a value set for a specific metafield.

However, the following line no longer retrieves a value:

line_item.product.metafields['app--1234567--hogehoge'].content_id

Has there been any change on Shopify’s side?

Could this update be affecting the retrieval of the metafield values?

I recently developed a theme extension that utilizes app metafields. The format I’m using is app.metafields.xxx_namespace .xxx_key
