Hi there! I understand you're having trouble creating a one-time Afterpay card specifically for Amazon purchases. Let's get this sorted out together.

To help me support you better, could you tell me:
- Are you getting any error messages when trying to create the one-time card?
- At what point in the process does the issue happen—when entering the purchase amount, generating the card, or using the card on Amazon?
- Have you tried removing any existing payment methods and creating a new card from scratch?

While you reply, here’s a general step-by-step guide to create a one-time Afterpay card for Amazon on your Android device:

1. Open the Afterpay app on your Android (OS 10) device.
2. Go to the ‘Orders’ tab or look for the option related to payments or virtual cards.
3. Select ‘Create Single-Use Payment Card’ or something similar.
4. Enter the exact purchase amount for your Amazon order. Double-check this amount because Afterpay recommends entering the precise total or a little more to cover any taxes or shipping fees.
5. Generate the card details. You should see a virtual card number, expiry date, and CVV.
6. Use these card details to pay on Amazon as you would with a regular credit/debit card.

Some common issues that block the creation of this card include:
- Having an expired or invalid primary card on Afterpay. Try updating your payment info.
- Network or app glitches—restart the app or your device and try again.
- Possible restrictions on your Afterpay account or limits reached.

If you’ve tried removing saved payment methods and the problem persists, you can also verify your Afterpay card’s activation status and ensure no blocks or restrictions exist on your account.

If none of these resolve the issue, I can dig deeper or help you escalate this to our specialist team. Just let me know!

Are you able to try these steps and share any error messages or behaviors you notice?
