Hey, yesterday (December 4, 2025), everything was working perfectly fine with Microsoft Edge. The Copilot chat in the sidebar panel used to greet me by my name (William), which meant I was properly logged in with my personal Microsoft account. But after I updated to the latest Edge version, now it just says a generic "Hey, nice to see you, what's new?" like it doesn't recognize me at all.
I want to know what's going on and how to fix it. When I try to paste a screenshot or image into the chat, it prompts me to "Sign in," but when I click the Sign In button, it's completely frozen, it doesn't redirect me anywhere, doesn't do anything, and just stays unresponsive. The "Maybe later" option works, but that's not helpful. I've tried restarting Edge, clearing cache, and logging out/in, but nothing changes. Any ideas on a quick fix, or if this is a known bug from the recent update? Thanks!
I don't even see my previous conversation, meaning that I am not logged on, because it won't let me

Vincent BOUQUET 5 Reputation points2025-12-07T13:20:25.3533333+00:00 I am experiencing the same issue described in this thread with Copilot in Microsoft Edge.
My setup: Microsoft Edge version 143.0.3650.66 (64-bit), personal Microsoft account, synchronization enabled in Edge settings.
Symptoms: Copilot in the sidebar no longer recognizes my profile. It only shows a generic greeting and prompts me to sign in, but the sign-in button is unresponsive. The "Maybe later" option works, but Copilot remains disconnected.
Steps already tried:
- Verified that Edge is properly connected to my personal Microsoft account.
- Confirmed synchronization is enabled in Edge settings.
- Cleared cache and cookies.
- Restarted Edge and Windows.
- Signed out and back in to my Microsoft account.
- Issue persists across sessions.
This problem started immediately after updating to version 143.0.3650.66. Everything was working fine before the update.
It seems to affect personal Microsoft accounts specifically, while Edge itself remains connected and synchronized.
Please confirm if this is a known bug in the latest Edge release and if a fix is planned.

Please check your profile sign in, turn on Sync for personalization, then go to Settings then Sidebar then Copilot to confirm your account shows there. If the Sign In button in the sidebar still freezes after you restart Edge, this matches a known issue from the latest update so keeping Edge updated and signed in will restore your conversations once the fix arrives.

SnW SniperWolf 5 Reputation points2025-12-06T17:51:35.95+00:00 I have the same problem as the OP user. All my conversation sessions are gone and Copilot is treating me like a new user, even though I was always logged in. This started right after the latest Edge update today. I still have all the sessions on my phone with the same Microsoft account, but conversations on my phone and in the Edge sidebar don’t sync at all. As power users, we’re frustrated with receiving generic replies, if we can find our way to these forums for help, we shouldn’t be treated like average Joe users. This is clearly a bug from the update and needs proper acknowledgment and a fix.

2025-12-06T18:36:18.3966667+00:00 have exactly the same problem. Yesterday Copilot in the Sidebar worked without any issues, I was signed in. Today it doesn’t - there’s not even an option to sign in, refresh Copilot, nothing.

jimmy carlin 0 Reputation points2025-12-07T20:28:17.04+00:00 Yesterday, pilot was fine. Knew my name. Now, the browser hardly remembers, and the sidebar knows nothing. I was using it to help me write my book. I don't know what to do.
