### Answer When you see the message "This version is already published We cannot change the conversation flow of a published version," it means you're trying to edit a published version of your agent, which is locked and cannot be modified. [(1) ]() To make changes, you need to create a new draft version. Once a version is published, the agent configuration for that version cannot be changed—you can only view it and create a draft version from it. Here's how to work with this: Option 1: The system should automatically create a draft for you When you publish an agent by clicking the "Deployment" button in the upper right corner, it creates a new version and automatically generates a new draft that you can edit safely. [(2) ]() Option 2: View and work with versions You can view old versions by clicking on the Clock icon in the upper right corner of the agent page. [(1) ]() From there, you'll see a list of all versions of the agent. When you're viewing a published version, you can create a new draft from it to continue making changes. Important note about drafts: Your conversation flow is always in draft mode until you publish. [(2) ]() When you publish, it creates a new draft that you can edit. If you select "Draft" in the Phone Numbers tab, it will always fetch the latest version of the agent. [(1) ]()
