Shopify Translate Checkout page
Checkout pages won't be detected by ConveyThis as they belong to another domain. Indeed, knowing that these pages are hosted by Shopify itself, translations will be directly handled on its side. In any circumstances, your checkout will be automatically translated in the related destination languages thanks to a mechanism we manage.
