Hi! Sorry to hear your GTBank app isn't working for you. To help you better, could you tell me a bit more about the issue? For example, is the app not opening at all, crashing, showing an error, or something else?

In the meantime, here are some common steps we can try on your Android 10 device with WebKit browser:

1. Restart Your Device: Sometimes a simple restart can clear temporary glitches. Press and hold your power button, then tap "Restart" or "Power off" and turn it back on.

2. Check for App Updates: Go to the Google Play Store, search for the GTBank app, and see if there's an update available. Updating can fix bugs.

3. Clear App Cache and Data:
- Go to Settings > Apps > GTBank app.
- Tap "Storage."
- Tap "Clear Cache" first and try the app again.
- If the problem persists, tap "Clear Data" — note this will reset the app and you may need to log in again.

4. Check Network Connection: Make sure you have a stable internet connection, either via Wi-Fi or mobile data.

5. Reinstall the App: Uninstall the app and then reinstall it from the Play Store. This can fix corrupted files.

6. Check Registered Phone Number: Ensure the phone number linked to your GTBank account matches the one you registered the app with; discrepancies can cause login issues.

If you’ve tried these already, please let me know exactly what you’ve done and what the app is doing now. That way, I can help you with more specific troubleshooting or escalate if needed1.

Are you able to try these steps and tell me what happens?
