Why is our sales channels app not working within Shopify admin anymore?

Hello @FarhanS ,

You need to make sure that your embedded app that you inserted into Shopify admin panel still responds with a header that has an allowance to be embedded outside the original domain. Something like header(‘Content-Security-Policy’, “frame-ancestors https://{$user- >name} https://admin.shopify.com”)
