Copilot update on 3rd Oct 2026

Alison 0

Since the new copilot update the chat that I have been building is appearing in the side bar but failing to load. Window says to refresh the page. This is an important chat widow can you please fix it for me. This a very important chat window, I have purchased an upgrade, but if I can no longer access the chat then I have wasted my money.

I have tried loading copilot in a private window on my PC and manually signing in, the same thing happens with the chat.
The difficulty loading also applies to my mobiles.

Hello Alison,

This behavior appears to be affecting multiple users following the recent Copilot update, and there are cases where conversations reappeared after several days, so it may be related to the chat history still syncing with the updated experience.

Here are some suggestions you can try:

Make sure you are signed in with the same account and sign-in method originally used for that conversation. Personal and work or school histories are kept separate.
Check the Copilot activity history in your Microsoft account. If available, export the activity data to check whether the conversation is still stored there. Please do not delete or clear the history.
In the meantime, please submit feedback through the Feedback option in Copilot. In-app feedback is the best way to send the problem and diagnostic details to the Copilot product team for further investigation.

Since this is a public user-to-user forum, Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas.

Thank you Norah. I did use the feed back. It seems to be a multi user problem, which may clear itself after several days. The mobile app is also problematic, it doesn't allow multi-device chat and requires starting a new chat when changing devices. Continually asks about privacy and ad preferences. I've uninstall and reinstalled multiple times. Now it's just uninstalled.

Thank you for the update, Alison.

Please make sure that each device is signed in using the same account and the same sign-in method. In the meantime, you may use the Copilot web version as a temporary workaround.

I hope the missing conversation becomes available again once the account update and synchronization are completed.

Thank you so much for your patience!
