Two of my existing copilot chats became inaccessible after the September 2026 update. one has been inaccessible for 25 days, from September 9th to October 4th. A second conversation was working after the update but after I added only 3-4 messages, it also became inaccessible, both are still in my history, but I cannot open them. this happens across my computer and phone.

    Welcome Zeke,

    Thank you for providing the details and screenshot. Since the same two conversations fail to open on both your computer and phone while other chats remain accessible.

    To better understand the problem, could you confirm:

    • Are you signed in with a personal Microsoft account (for example, Outlook.com, Hotmail.com, Live.com), or a work/school account?
    • Can you create and use new Copilot chats normally, or do they eventually become stuck as well?
    • Have you already tried opening the affected chats from both https://copilot.microsoft.com and the Copilot mobile app while signed into the same account?

    In the meantime, please try these quick checks:

    • Open Copilot in an InPrivate/Incognito browser window and attempt to open one of the affected conversations.
    • Sign out of Copilot completely, then sign back in and test the affected chats again.
    • On the web version, clear the browser cache and cookies for Copilot, then refresh the page and try opening the conversations.

    I look forward to your update.
