ayaecofashion review for Amazon MCF and Buy with Prime

The app is currently unusable. It is stuck indefinitely on "Loading catalog data in progress." After inspecting the console, I found a major authentication flaw in your API connection: {"message":"1 validation error detected: Value null at 'shopifySessionToken' failed to satisfy constraint: Member must not be null"}. How is it possible that the session token is null when the connection is through Shopify's own platform? Furthermore, the API response confirms that the operation bulk_fulfillment_update for my domain (ayaecofashion.myshopify.com) does not exist. This lack of maintenance is directly affecting my sales and inventory management. Please address this backend failure immediately.
