Hi there! I understand you’re seeing just a blank screen when trying to open the Whataburger app on your Android 10 device with WebKit browser. Let’s work through this together to get it fixed.

To start, could you let me know if the app ever loads past that blank screen, or if it stays stuck there every time? Also, have you recently updated the app or your device?

In the meantime, here’s a step-by-step approach to try:

1. Force Close and Restart: Close the app completely from your recent apps and reopen it to rule out temporary glitches.

2. Clear Cache and Data:
- Go to your phone’s Settings.
- Tap Apps or Apps & notifications.
- Find and tap Whataburger app.
- Select Storage & cache.
- Tap Clear cache, then Clear storage or Clear data.

This will reset the app’s stored info, but won’t delete your account.

3. Check for Updates: Open the Google Play Store, search for Whataburger, and see if there’s an update available. Installing the latest version can fix bugs.

4. Restart your Phone: Sometimes a fresh restart clears app or system issues.

5. Reinstall the App: If the problem persists, uninstall the app completely and reinstall it from Play Store.

If after these steps the blank screen remains, it might be related to app compatibility or a known issue. Let me know how it goes, and we can check if there are any ongoing reports about this problem or dig deeper.

Are you able to try these and update me?
