Navigate to Manage > Edit Tab > Settings > Version Tracking
Shows the most recent available versions. Allows you to preview any of the available version by clicking on the preview icon.
Click on the rollback icon to rollback to any of the previous version. A new version is automatically created by copying the content from the rollback version.
By default, Live Tab keeps up to 5 previous versions for history.
