Language
One language for the portal
An administrator sets the app language and it applies to the whole portal: the settings, the tab and the planner. It is not a personal preference.
An explicit Czech or English choice wins. When the administrator leaves the choice to the portal, Czech applies for a portal language of cs, sk or cz, otherwise for a .cz domain, and English in every other case.
The tab and menu names exist in both Czech and English.
This website
The public pages have their own CS | EN switch. The switch stores a cookie in the browser. It does not change the language inside Bitrix24.
The page you are on
The manual follows the language of the address (/cs/ or /en/). The language in the app and this website are independent.
