By turning the Chat Persistence on, the chatbot will persist the chat session across pages when it is on the same domain. So when a user who interacted with the chatbot on one page, moves to a different page or exits sessions and comes back, the chatbot will show the conversation that was left off
Having chat persist across all sessions means that users can rejoin and resume the conversation WITHOUT having to scroll up, or remember specific previous conversations.
Turning Chat Persistence On:
Persistence can be found under Customise your Bot further > Preferences > Persistence.
Simply turn the toggle on to switch Chat Persistence on for your chatbot.
