Hello
Thank you for posting in Q&A forum
One suggestion is to try accessing Copilot through a web browser instead of the app.
Sometimes, using the web version can bypass issues related to app caching or profile settings,
You can also try using in-private browsing or incognito mode to see if that helps.
if web browsing still has same issue, you can try to clear your browser’s cache and cookies to see if issue will fix.
New copilot app can't switch from work to personal account - Microsoft Community Hub
