By default, Rich Returns will detect the customer language based on the browser language set by the user and display the customer portal accordingly in different languages. This approach is the most widely used in eCommerce (e.g., by Amazon) and most user-friendly since it respects the user's settings.
Find the pre-translated languages in the Rich Returns Dashboard under Translations / Languages.
