We use Dynamics 365 Portals with 2 languages (fr-FR / en-US). We have 3 websites, and we remark that when accessing 2 websites with their urls, the browser add systematically the language to the URL : https://url/fr-FR, but for the 3rd website, the language is not added to the url.
Did we miss any configuration in the 3rd Website that avoid the browser to add the language code to the URL ?
Thanks.
