Hi! I see you’re encountering the Wawa app error code P974001 on your iPhone with iOS 26.0. That error often relates to payment or card information issues. To help you best, can you tell me what you were trying to do when the error appeared? For example, were you adding a credit card, placing an order, or trying to fuel up through the app?

While you provide that, here are some common steps to fix error P974001 that you can try:

1. Check Your Payment Info Carefully:
Make sure the billing address you entered exactly matches what your credit card issuer has on file — including abbreviations like “Rd.” vs “Road” and any punctuation. Slight differences here can trigger errors.

2. Update the Wawa App:
Head to the App Store and check if there's an update available for the Wawa app. Using the latest version can fix bugs causing errors.

3. Restart the App:
Close the Wawa app completely (swipe it away from the app switcher), then open it again.

4. Reinstall the App:
If the problem persists, try deleting the Wawa app and reinstalling it fresh from the App Store. This can fix corrupted app files or cache.

5. Check Your Internet Connection:
Sometimes, unstable or slow connections can cause order or payment errors. Try switching between Wi-Fi and cellular data to see if it helps.

6. Contact Your Bank or Card Issuer:
If adding a card is the issue, sometimes the bank may block transactions or require verification. Double-check with them that there are no holds or restrictions.

If you’ve already tried some of these steps or if the error popped up during a specific action, please let me know, and we can dig deeper to solve it.

Are you happy trying these steps first? If not, or if the issue remains, I’ll guide you further.
