Microsoft Edge Copilot Sidebar Temporarily Unavailable Due to Migration

Several Microsoft Edge users have reported that the sidebar Copilot is temporarily inaccessible, showing a prompt indicating a backend migration to a new experience that may take a few days. Affected users are currently advised to use the web-based version of Copilot while the rollout is underway. This temporary disruption highlights the ongoing backend updates as Microsoft works to deeply integrate and unify its AI assistant across various products like Edge, Windows, and Microsoft 365. Users relying on the browser-integrated AI for daily tasks may experience minor workflow interruptions until the rollout completes. When attempting to click Copilot, users encounter a specific message stating 'Your Copilot is migrating to the new experience.' As a temporary workaround, restarting the browser or switching directly to copilot.com is recommended.
