Arrives By is fully compatible with Shopify's Translate & Adapt app.

First, make sure that the Delivery Time app block is saved on your product page.

From the Translate & Adapt app, go to the "Theme" section and select "Templates".

Select "Product" to see the available translatable options.

You can customize the different settings for Delivery time here. You will need to add translations for every language your shop uses. If there is no translation, it will default to English.
