I buit my agent as a chatbot for our event. After it was published, everthing went well, except we found an outdated information in one of our files uploaded. So I DELETE the old file and upload a new one. But then I couldnt find the "Publish" button anymore, which is supposed to locate in the top right corner. I've tried using the new search engine, zooming out my screen 80-90%, clearing my cookie, or private browsing. But none of them worked. So the chatbot just keep answering with the wrong information. Since my event is coming up, and the chatbot link is already sent out to our customers. Is there anyone could help fix this issue. Thanks a lot.
