One common query is whether pre-order features support translation apps. Unfortunately, as of now, pre-order functionality typically does not have built-in support for translation apps. This means that if you have a store with multiple language options and you use a translation app to convert your product descriptions, checkout pages, and other store elements, the pre-order feature may not automatically adapt to these translations.
If you are using a single language on your store you can translate the inline text in the settings check the image below for reference.
