Hello! I’m Pierre, here to help you get the PECO app working smoothly again. To start, could you tell me a bit more? For example, does the app crash immediately upon opening, or only after certain actions? Also, have you noticed if this happens after any recent updates or changes to your phone?

Meanwhile, I can guide you through some common troubleshooting steps for Android 10 on your WebKit browser:

1. Force Stop the PECO App:
- Go to your phone’s Settings > Apps > PECO app.
- Tap on "Force Stop" to stop it completely.

2. Clear Cache and Data:
- In the same app info screen, tap "Storage & Cache."
- Select "Clear Cache" first, then if needed, try "Clear Storage" or "Clear Data" (note: clearing data will log you out).

3. Restart Your Phone:
- Sometimes a simple reboot can refresh the system and clear temporary issues.

4. Check for PECO App Updates:
- Open the Google Play Store, search for PECO, and make sure the app is updated to the latest version.

5. Update Your Android System Software:
- Go to Settings > System > System update and check for any available updates.

6. Reinstall the PECO App:
- If problems persist, uninstall and then reinstall the app. This can clear corrupted files.

If you've already tried some of these, let me know so I can suggest more tailored steps. Also, ensure your internet connection is stable as sometimes connectivity issues may cause app crashes.
