Solution 1Recommended

Reinstall the Copilot App and Check Network Settings

Resolve common app data glitches or network connectivity issues that prevent successful sign-in.

Often, signing into a new device can trigger authentication blocks due to corrupted app installation data or unstable network connections. A clean installation combined with network troubleshooting usually resolves this.

1
Switch Internet Connection

Disconnect from your current Wi-Fi network and switch to mobile data (or vice versa) to rule out network restrictions blocking the Microsoft authentication servers.

2
Restart the Phone

Power off your new Android device completely, wait a few seconds, and turn it back on to clear any temporary system glitches.

3
Reinstall Copilot

Navigate to the Google Play Store, search for Microsoft Copilot, uninstall the existing app, and then download and reinstall the latest version.

4
Sign In Again

Open the newly installed Copilot app and attempt to sign in using the Microsoft credentials tied to your active subscription.

Frequently Asked Questions

Why does my Microsoft 365 Copilot subscription show as inactive?

Subscriptions can appear inactive if they have expired, if a payment failed, or if you are logged into a different Microsoft account than the one used for the initial purchase. Check your account dashboard online at account.microsoft.com to verify your current status.

Does Copilot work on older Android versions?

Microsoft Copilot requires a recent, supported version of Android to function properly. If your device software is heavily outdated, the app may crash or fail to authenticate securely during the sign-in process.

How do I clear the cache for the Copilot app on Android?

Go to your Android Settings > Apps > Copilot > Storage, then tap 'Clear Cache'. This can resolve minor data corruption issues preventing sign-in without requiring you to completely uninstall the app.
