Got it here. Thanks Phil B. said: Vince, once you upload your English translation file to the git repo it will then be uploaded to Crowdin, our translation service. Once it's there, it will be up to the translators to translate it into their own language. As they do that, it probably won't be all at once, the strings that are translated will show up in the translated language instead of English (the default) depending on what the user has selected as their language in the account settings. If you're seeing the red text, that means the key is missing and needs to be added to the translation JSON. You can find this on the campaign settings page, there is a new tab, Translation, next to where you edit the HTML and CSS now.
