General

The language preference from a store account is retrieved and set when a store account logs in. This is only the case for store accounts related to contacts and customers (not Sales Representatives).
The language preference of a customer is retrieved from the customer card. Open a customer card and click on the 'Foreign Trade' tab. Here you will see the field 'language code' where you can set a default language for this customer.

Remember that a customer always can overwrite the default language or own language preference on the website by selecting a different language in the language dropdown.

Sales Representatives do not have their own language; their language is the one which is selected in the language dropdown in the webshop.
