Chats disappearing and conversations getting scrambled after new Copilot update
Your missing and partial chats across web and mobile are consistent with the updated Copilot experience still moving account content. First confirm every device uses the identical personal account and sign-in method; Google, Apple, and Microsoft paths can represent different histories. Do not delete history while investigating. Check for an in-app link to older chats, restart Copilot, and allow time for migration to complete. Then use the Microsoft privacy dashboard to export all Copilot activity history, giving you a copy of retained prompts and responses. Signed-in conversation history is retained for 18 months, but retired Group Chat content does not carry forward after the 2026 app change. If ordinary chats remain incomplete, use Copilot’s ellipsis menu > Send feedback > Report a problem. Include when the loss began, affected chat titles, device versions, and screenshots. There is no documented client-side restoration tool, so Microsoft must investigate persistent server-side loss.
The problem is very bad and still ongoing and it is 21st. I did not check old conversation but things are disappearing even when the chat is open. It happened several times that I look back and the last 1-2 interactions are missing and when I am asking again the chatbot says 'as I said previously'. So now I am asking the chatbot to retrieve pieces of conversation
