## Short answer
Most card failures are due to 3‑D Secure (SCA) not completing. Confirm the bank app prompt, or try a different method.
## Steps
- Approve the **3‑D Secure** prompt in your **banking app**.
- If you’re in a **Facebook/Instagram in‑app browser**, tap ••• → **Open in Browser**, then retry.
- Try another method (e.g., **PayPal** or a different card).
- Clear cache/cookies, then retry.
- Check the **billing ZIP/Postal** matches your card.
## If/Then
- **If you see a charge but the order failed** → it’s usually a temporary hold that auto‑reverses in **1–3 business days**. If it doesn’t, share a statement screenshot and we’ll help.
- **If your bank declines** → contact your bank to allow the transaction, then retry.
## What we need from you
- Checkout email
- Device + browser
- Time of the attempt and any error message/screenshot
## Notes
- Social in‑app browsers can break 3‑D Secure; using your device’s main browser is more reliable.
