Hi there! I’m sorry to hear that you’re having trouble loading your credit card into the Passport Parking app. Let’s work together to get this sorted out.

First, can you tell me if you’re using Wi-Fi or a cellular data connection when you’re trying to load your cards? Sometimes, network errors can happen due to connectivity issues.

Here’s a general troubleshooting process we can follow:

1. Check Your Connection:
- If you’re on Wi-Fi, try switching to cellular data, or vice versa. This can sometimes resolve the network issues.

2. Clear the App Cache:
- If you’re using the app, you may want to clear its cache. Here’s how to do it:
- Go to your device settings > Apps > Passport Parking.
- Tap on “Storage” and then “Clear Cache.”

3. Update the App:
- Ensure you have the latest version of the Passport Parking app. Sometimes issues arise from outdated versions.

4. Install App Again:
- If clearing the cache doesn't work, you can also uninstall the app and reinstall it. This can refresh everything and fix potential bugs.

5. Try Later:
- If it’s still not working, it might be a temporary issue on the Passport Parking server side. Waiting a bit before trying again can help.

If you try these steps and still encounter the same issue, please let me know, and we can explore further options such as checking for account issues or contacting higher-level support.

Are you satisfied with the solution I provided?
