Worked as intended. I was enrolled in a pilot to test additional features and the onboarding and communication was great and responsive.
Thank you so much! We're so happy the app is serving you well and appreciate your participation and activation of the additional features!

At first, we struggled to get the app working and installed and uninstalled it a few times. But once we followed the basic setup instructions properly, it worked flawlessly. Previously, we were manually entering order details to fulfil orders through Amazon MCF. Now, every time we get an order in the UK or the US, we just click a button in Shopify. It has completely changed our workflow and allowed us to focus on growing the business instead of managing fulfilment. We were even thinking about setting up our own warehouse, but now 90% of our shipments go through Amazon services via this app.
Thank you so much! We're so happy the app is serving you well in the US and UK. We're also making additional countries available in April if applicable to your business.

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.
Thank you for taking time to share feedback and surface this issue. Our team is actively looking into resolving it, and we will updated as soon as we can when fixed. 2/19 - Thanks you again for sharing feedback and letting us know about the issue. We have resolved it and would like to invite you to use the app - please let us know how we can help get you started.

Why is shipping speed mapping not available?
Thank you for taking the time to share your feedback. Shipping speed mapping is available in the app: 1. On the app home screen, select 'Configure shipping options'. 2. At the bottom of the shipping options page, you'll see all shipping rates you've configured for your store (across all shipping profiles). For each rate, you can select the MCF speed you'd like to apply by opening the drop-down menu in the 'Shipping speed' column. Please don't hesitate to reach out to our support team directly if you have any additional questions or would like more guidance.
