- Product
- Microsoft 365 Copilot Mobile App
- Device & OS
- not provided
- Scenario
- Attempting to open files or use the Notes feature within the mobile application.
- Observed behavior
- The application crashes, closes unexpectedly, or fails to open the requested files, and standard troubleshooting like restarting or clearing the cache does not resolve it.
Ensure you have your device model, operating system version, and the exact Copilot app version noted down, as this information is required to properly report the defect to Microsoft.
Submit a Detailed Bug Report to Microsoft
Since standard troubleshooting steps like clearing the app cache do not resolve this update-related defect, the best course of action is to report the crash directly to the development team.
Some Copilot features are constantly evolving. When an update breaks functionality and causes a crash, community support cannot patch the app. Submitting detailed logs and reports helps developers investigate and release a fix in the next update.
Find and note your current Copilot app version, device model, operating system version (e.g., iOS 17 or Android 14), and the date the app was last updated.
Navigate to the official Microsoft Copilot feedback portal via a web browser, or use the in-app feedback option if the application stays open long enough to reach the settings menu.
Provide a clear, step-by-step description of how the crash occurs specifically when opening the Notes feature, and submit your report.

Frequently Asked Questions
Why does clearing the app cache not fix the Copilot crash?
Clearing the cache resolves issues caused by temporary data corruption. If the crash stems from a bug introduced in the recent app update's code, a developer patch is required to fix the underlying defect.
Can I roll back to a previous version of the Copilot app?
On Android, you may be able to uninstall the current version and sideload an older APK, though this is not officially supported. On iOS, rolling back to previous app versions is generally not possible without a specific backup.
How long does it usually take for Microsoft to fix app crashes?
Resolution times vary depending on the severity of the bug. Critical crashes affecting many users are often patched within a few days through a minor update in the app store.
Will I lose my notes because the Copilot app is crashing?
Notes linked to your Microsoft 365 account are typically synced to the cloud. You should be able to access your data safely via a web browser or desktop application, even if the mobile app fails to open.
