SharePoint: Simplified editing of user interface elements in multilingual communication sites
In 2020 we rolled out the multilingual communication site feature which allowed a site owner to enable multiple languages for page and news publishing in a SharePoint communication site.
With this update, a user with appropriate edit permissions can update selected multilingual user interface (MUI) elements in all the languages enabled in a multilingual communication site in the same editing session. MUI elements enable users to see and use SharePoint site interfaces in the language they prefer, instead of the default language that was selected when the site was created.
