I am trying to disable the native order tracking area on my thank you page as I have a separate custom order tracking page/app and the native tracking is routing my customers elsewhere. See image.
Is there a way to simply not display this section (since I don't have access to the thank you page theme file) by adding an additional script in my Checkout Settings?
I've already reached out to Shopify directly here, whose advice was to upgrade by Shopify plan :/
I don't think there is an option for that in Shopify.
But yes, you can do that using the Shipment tracking & notify app. The app allows you to create a "Track your order" page from where your customers can track their order. Once you fulfill the order, Shopify sends an email with the link to the order status page. When this link is clicked, it will direct you to the thank you page as you have shown.
But once you use the app, when your customer click on the link, it will direct you to the app's "Tracking page" from where your customers can see the order status.
