Your app language changes the Calder interface. Your Mission languages are the languages you can use to complete Missions.
Your app language, also called the interface language, controls which language the Calder interface is displayed in. You choose a single app language.
Mission languages are the languages you can comfortably use when completing Missions. You can choose more than one Mission language.
A Mission owner may target All languages, which means the Mission is open regardless of the languages in your profile. Changing your app language does not change your Mission languages, and changing your Mission languages does not change the interface.
