Hi! I see your Polaris Office app just stopped working. Could you share a bit more about what happened? For example, did the app crash, freeze, or fail to open? Also, have you tried any fixes so far? That way, I can guide you better on what to do next.

Crash and freeze

Thanks for the details! Since Polaris Office on your Android 10 device is crashing and freezing, let's try some steps to get it back to working smoothly.

1. Restart the device: Sometimes a simple reboot clears temporary glitches. Please turn your device off, wait about 30 seconds, then power it back on.

2. Clear app cache:
- Go to your device's Settings.
- Tap Apps & notifications (or just "Apps").
- Find and select Polaris Office.
- Choose Storage & cache.
- Tap Clear cache (not Clear data yet).
Then try opening the app again.

3. Clear app data if cache didn't help:
- Repeat the steps above, but this time also tap Clear storage or Clear data.
This will reset the app to default settings and remove any corrupted temporary files. Note, this might erase your offline documents stored in the app, so make sure you back up important files if possible.

4. Update the app:
Visit the Google Play Store and check if an update for Polaris Office is available. Sometimes bugs causing crashes get fixed in newer versions.

5. Check storage space:
Make sure your device has enough free storage, as low storage can cause apps to crash.

6. Reinstall Polaris Office:
If the above steps don't solve the problem, uninstall the app completely, then reinstall it fresh from the Play Store.

Please try these and let me know how it goes. If the app still crashes or freezes, we can look into more advanced solutions or check for server-side issues.

Are you able to try these steps now?
