Hi there! I understand you're having trouble using the Park app to park. To help you better, could you please tell me a bit more about the problem? For example:

- Are you seeing any error messages when you try to start a parking session?
- Is the app not responding or crashing?
- Is it a payment issue or a location issue?
- Have you been able to use the app successfully before, or is this your first time trying?

These details will help me guide you through the right steps. Meanwhile, let's start with some quick checks that often resolve issues:

1. Restart your iPhone — sometimes a simple reboot fixes glitches.
2. Make sure your Park app is updated to the latest version via the App Store.
3. Check that your internet connection (Wi-Fi or cellular data) is stable.
4. Log out of the app, then log back in to refresh your session.
5. If these don’t help, try uninstalling the app and reinstalling it — but sign in again afterward.

Could you try these and let me know what happens? If you see any specific error messages, please share them with me. That will help us dig deeper if needed.
