Hello! I see you're having trouble with the UK ETA app not accepting your credit cards. That can definitely be a problem when trying to complete your application. To help you better, could you please tell me:

- Are you getting any specific error message when trying to pay?
- Which type of credit card are you using (Visa, MasterCard, American Express, etc.)?
- Have you tried more than one card or different payment methods?
- Is this happening specifically on the app or have you tried the website too?

Meanwhile, a common workaround I’ve noticed is that the UK ETA app sometimes has issues processing payments, but applying directly through their official website often works better. It avoids the app’s payment glitches altogether.

Here’s a quick step-by-step you can try:

1. Open your web browser on your Windows device and go to the official UK ETA website (rather than the app).
2. Start the application process and proceed to the payment section using your credit card.
3. Make sure your card details are entered correctly and that your card is enabled for international or online transactions if applicable.
4. If the website also declines the card, try using a different card or payment method if possible.
5. Sometimes clearing your browser cache or trying a different browser may help with payment page issues.

If these steps don't resolve the problem, it may be related to the app's known payment issues or restrictions on certain cards. In that case, using the website is the best workaround. Also, double-check if your bank has placed any restrictions on payments to UK government services.

If you continue facing issues with both the app and website payments, please let me know. I can then guide you through some advanced troubleshooting or help you contact UK ETA support directly at [email protected] for payment-specific assistance.

Does this sound okay? Could you tell me a bit more about what you’ve tried so far?
