Hi there! I understand you're able to use the BURGER KING app, but it runs into an issue when you try placing an order, showing an error message that they're working on a fix. I want to help you get past this smoothly. Before I suggest solutions, can you tell me if this happens every time you try to place an order or just sometimes? Also, have you noticed if the app charges your payment method despite the failure?

Once I have those details, I can guide you through some useful steps tailored to your Android 10 device with WebKit browsing.

In the meantime, here’s a general step-by-step approach we can try together:

1. Check App Version & Update: Ensure your BURGER KING app is updated to the latest version from the Google Play Store, as updates often fix bugs affecting ordering.

2. Clear Cache and Data:
- Go to your phone’s Settings > Apps > BURGER KING.
- Tap on Storage, then Clear Cache.
- If the issue persists, try Clear Data (note: this will reset the app, so you may need to log in again).

3. Restart Your Device: This can refresh your system and network connection.

4. Verify Payment Information: If payment fails, ensure your saved card details are correct and not expired. Sometimes, issues at the bank side can block transactions.

5. Try a Different Network: If possible, switch from Wi-Fi to mobile data or vice versa to check if connection issues cause the problem.

6. Uninstall and Reinstall the App: A fresh installation can fix corrupted files.

If you've already tried any of these, please let me know so I don't repeat steps. There are known cases where the app’s ordering system has temporary server issues, in which case it might require some time or direct contact with their digital support team. If the app charges you but doesn’t complete the order, refunds usually process within 24 to 72 hours, but saving screenshots is a good precaution1.

Feel free to update me with what you’ve tried or observed, and we’ll find the best next step! Are you satisfied with this initial guidance?
