Copilot Stop working

Fully close and reopen the Copilot mobile app first; if the screen remains blank, test a different network and the Copilot web client to determine whether the failure is limited to the app.

Troubleshooting sequence

1. Force-close Copilot
   • Open the phone’s recent-apps/app-switcher screen.
   • Swipe Copilot away, then reopen it.
   • Microsoft’s current guidance recommends quitting and reopening Copilot when the updated app does not load correctly.^1^
2. Change networks
   • If connected to Wi-Fi, disable Wi-Fi temporarily and try mobile data.
   • If using mobile data, connect to a different Wi-Fi network.
   • A mobile Copilot case recommends this test to identify whether the current network is preventing the app from connecting.^2^
3. Test Copilot outside the app
   • Open the phone’s browser and visit https://copilot.cloud.microsoft.
   • Sign in using the same account.
   • Copilot officially supports both mobile apps and web access.^3^
   Interpret the result:
   • Web works: The account and service are accessible; continue with the app-specific steps below.
   • Web is also blank or cannot sign in: Try another network. For a work or school account, contact the organization’s IT administrator because proxies, firewalls, Conditional Access, tenant restrictions, or app-control policies can block Copilot.^3^
4. Check the selected account
   • If the app menu is accessible, open the profile/account switcher.
   • Confirm whether it shows Personal or Work, and select the account you intended to use. Copilot supports both account types, but their experiences and data remain separate.^4^
   • Sign out, completely close the app, reopen it, and sign in again. If the account uses Google or Apple authentication, select the same Continue with Google or Continue with Apple method previously used.^1^
5. Update, then reinstall Copilot
   • Open the App Store or Google Play Store and install any available Copilot update.
   • If no update resolves it, delete Copilot, restart the phone, and reinstall the official Microsoft Copilot app. Reinstallation is a documented mobile troubleshooting step for app-file or local-data problems.^2^

If it remains blank

If the menu becomes available, select … → Send feedback → Report a problem. Include:

• Phone model
• iOS or Android version
• Copilot app version
• Whether Wi-Fi and mobile data produce the same result
• Whether the web version works
• A screenshot of the blank page
• Approximate time the problem began

Microsoft specifically requests the device, operating system, start time, and screenshot when reporting persistent Copilot app problems.^1^
