What is system language?

System language is the language that is set as the default for the system and will be the language that all users get when they are invited.

If you change the language on your own user profile, the language you set there will override the system language.

That way, you can have a standard language, but where users can change to their own preferred language.

The language that is set affects the system, e-mails, push messages, but the language must be set on the app regardless of the web solution.
