My app will be used by both English and Spanish users. How do I set up multi-language support for my app?
You can manage the supported languages for your app in the editor under App Settings -> Languages. Simply enable additional languages.
The platform will automatically translate any hard-coded strings in the container such as "Diagnostics" and "About". However you need to manage your own translations for any other strings. You can learn how to do that here: https://docs.journeyapps.com/reference/container/translations#application
