What happens when I change my primary language?
Your "primary language" is used to set which language you are recording in and which language messages should be translated into. This can be set in your user settings or changed by tapping the flag on a conversation. Changing the primary language will change it for all conversations.
In the example below, Nate had his primary language set to Italian and recorded an audio banter. The current user's primary language is English, so they see the message translated from Italian to English.
