ayaecofashion review for Amazon MCF and Buy with Prime

Feb. 16, 2026

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.
