How to access it
Open the Checkout dashboard in Aftersell and click Edit branding at the top of the page.Editing branding here requires a Shopify Plus plan. Shopify only lets apps read and write checkout branding on Plus, so on other plans these settings cannot be saved. If your store is not on Plus, make the same changes in the Shopify checkout editor instead: Settings → Checkout → Customize in your Shopify admin.
