By skyforbes Has anyone else had chats disappear on them mid chat? I switched from 5.1 to 4o to 5.1 during the day—each a separate chat. In the last, 5.1 chat, I had just given « thumbs up » for useful content, then gave thumbs down for the next response which seemed to have lost context, and then the entire chat disappeared. Only logged in on the one computer. Is this common?
