I have created a chatbot and published it on my team but now I want update some content from that power virtual agent chatbot and republish it .How can I get updated content in chatbot without typing the start over trigger.Help me to solve this issue.
I'm not sure I follow what you are asking. If you update the chatbot and Publish a new version then the next time the chatbot is invoked it will use the new definition. Existing conversations will continue to use the old definition. But all chatbots will time out after a certain amount of inactivity. So it shouldn't take more than a day for the new definition to be used everywhere.
If you are opening a new chat with the chatbot, as opposed to typing into an existing one you should not need to type start over. You only need the start over if the chatbot is still running in an existing instance.
