If you're experiencing issues with the Sunoco app where none of the buttons are working, preventing you from creating an account or submitting issues, follow these steps to troubleshoot:

1. Check for Updates: Ensure that the Sunoco app is up to date. Go to the Google Play Store, search for Sunoco, and see if there is an update available. If yes, install it.

2. Restart Your Device: Sometimes, a simple restart can resolve app issues. Turn off your Android device and turn it back on.

3. Clear Cache and Data:
- Go to Settings on your device.
- Navigate to Apps or Application Manager.
- Find and select the Sunoco app.
- Tap on Storage.
- Click on Clear Cache first, then Clear Data (Note: Clearing data might require you to sign in again).

4. Check Internet Connection: Ensure you have a stable internet connection. Try switching between Wi-Fi and mobile data to see if it makes a difference.

5. Reinstall the App: Uninstall the Sunoco app completely and then reinstall it from the Google Play Store.

6. Try Incognito Mode: If using a browser version, try accessing Sunoco's services in incognito mode to bypass any cache issues from the browser.

7. Test Another Device: If possible, try accessing the Sunoco app or website from another device to check if the problem persists.

8. Contact Customer Support: If none of these steps work, consider reaching out to Sunoco customer service. You can contact them through their Contact Us page or call their support line at 1-800-2SUNOCO for additional assistance - learn more.
