We are soon launching language versions of our learning experience (May 2025). We have a main portal in English, but will be offering the same content in various additional languages on other organizations. For this, we would need to be able to change the default language per organization. According the Support Forum, this is currently not supported. 
As a company selling worldwide, and offering learning experiences worldwide, we urgently need this option included. 
Please, may I ask to prioritized this request, as I also saw some other comments/ suggestions here with the same / similar aim.
Thank you for considering this.
