Hi there! I understand you’re having trouble signing into the Wawa app because it’s blocking you. To help you get this sorted out, could you please let me know if you see any specific error messages or codes when you try to sign in?

In the meantime, I can guide you through some common steps that often resolve this kind of issue on macOS (OS X 10.15.7):

1. Check Date and Time Settings: Make sure your Mac’s date and time settings are correct and set to update automatically. Sometimes incorrect system time can cause authentication problems.

2. Disable VPN or Firewall Temporarily: If you’re using a VPN or have firewall settings enabled, try turning them off briefly. These can sometimes block the app’s communication with Wawa’s servers.

3. Restart the Wawa App: Close the app completely and reopen it. If you’re using the browser version through your Mac, close the browser tab and try again.

4. Clear Cache or Reinstall: If restarting doesn’t help, try clearing your browser cache or reinstalling the Wawa app if you have it installed via a compatible method on your Mac.

5. Reset Password: Sometimes being blocked can be linked to credential issues. You can try using the "Forgot Password" option to reset your login details.

6. Contact Wawa Support: If none of these work, it might be best to contact Wawa support directly. They can verify if your account has been locked and assist with unlocking it safely.

If you want, I can guide you through these steps or help initiate contact with support. Just let me know! Are you seeing any error messages right now?
