Translating your order status page
You have the same control over the language used on your order status page that you do over the rest of your Shopify store. If you translated your entire theme language, then your order status page is already in your chosen language.
You can also translate your messaging line by line if the default text doesn't fit your branding. For example, the first line of the order status page reads "Thank you, John", but could be translated to "Thanks, John!".
Follow Change the wording in themes to customize your translations and wording. The order status fields are under the Checkout and system tab from the Checkout thank you heading to the Checkout shop policies heading.
