Recently I have been experiencing a problem with Copilot as it keeps removing latest messages we had in the chat.

    This behavior can happen when Copilot loses older or recent chat context in the current thread, or when chat content is still syncing in the updated Copilot app.

    Try these steps:

    1. Start a new chat session In some Copilot experiences, starting a new chat can help restore normal behavior after a thread becomes unstable or loses continuity.
    2. Restart the app or refresh the page Close Copilot completely and reopen it. On the web, refresh the page. This is one of the recommended steps when chats or content do not appear correctly.
    3. Check that the same account is signed in Make sure the app is using the same personal account previously used with Copilot. If multiple personal accounts are used, chat history can appear different between accounts.
    4. Allow time for content to sync or finish moving If the account is being updated to the newer Copilot experience, chats and content may still be moving. During that time, some chats may appear missing or show up differently across devices.
    5. Use any in-app link to older chats if shown If Copilot displays a message that chats are still on the way, use the in-app link to access previous chats and content while the move completes.
    6. If using multiple devices, compare them after restart Data movement can take time to complete across devices. After restarting Copilot on each device, check again.
    7. Report the issue from the app if it continues In the Copilot app, select the ellipsis (…) in the upper-right corner, then select Send feedback > Report a problem. Include when the issue started, the device and operating system, and a screenshot.

    If the problem happens specifically after switching tabs or windows, the most relevant supported actions are to restart Copilot, confirm the correct account, try a new chat, and report the problem with timing and device details so it can be investigated.
