The language section allows you to enable RTL for languages that require this. If you want to make changes to the app language file or create one for your language you can also upload a new version here and we’ll include it in your app. The language file needs to be included in the app binary, so making changes to it requires re-building and publishing a new version of the app.
If you want to make changes,
Download the file, update it, then re-upload to your app in Origami App Builder.
