Iam not able to sign in at Microsoft copilot in chat section of Microsoft edge. Iam already login to copilot app in windows and also if I open copilot webpage, there Iam also login but when I click to login in chat section of edge, nothing happens.

Please suggest me how can I login here as I need it because without login Iam not able to upload pdf files and it becomes very inconvenient to every time open copilot app or web page to perform any task.

The problem arised since yesterday when edge updated to latest version of 143.0.3650.66 (Official build) (64-bit)

I even tried to modify and reinstall the edge using system settings but problem still continues. User's image

    It seems the issue is caused by the recent Edge update affecting Copilot integration. Here’s what you can try:

    Clear Edge cache and cookies: Go to Settings → Privacy, search, and services → Clear browsing data → Select cookies and cached images.

    Sign out and back in: Completely sign out from Microsoft accounts in Edge, then sign back in.

    Check extensions: Disable any extensions that might block scripts or pop-ups.

    Try InPrivate mode: Open Edge InPrivate and see if Copilot chat works there.

    Update Windows: Make sure your system is fully updated, as Copilot sometimes relies on system components.

    If it still doesn’t work, contact Microsoft Edge support, they can provide a fix for this login bug.

    I'm having the same problem, it seems to be a general bug! Very annoying!
