Hi there! I understand that when you're trying to input your license plate number for CLT+ verification or when proceeding to payment, the license plate number deletes itself. That sounds unusual, and I'd like to help you get this sorted out.

To assist you better, could you tell me if this issue happens when you're using a particular browser or device only? Since you mentioned your device is a Macintosh running OS X 10.15.7, are you using Safari, Chrome, or another browser to access the CLT+ system? Also, have you tried entering the plate number on a different browser or clearing your current browser's cache and cookies?

This info will help me tailor the troubleshooting steps for your setup. Meanwhile, here’s a simple step-by-step to try:

1. Clear your browser cache and cookies. This helps remove any temporary files that might interfere with form inputs.
2. Try entering your license plate number again in the input field, making sure there are no extra spaces or special characters.
3. Proceed to the payment step and see if the plate number remains in the input field.

If this doesn't fix it, there might be a glitch in the CLT+ system itself, or perhaps an issue with how the site handles sessions or inputs. Let me know if you’ve already tried clearing cache or switching browsers, so I can guide you through more advanced solutions or direct you to CLT+ support if necessary.

I use safari, have re-started my computer, and also tried on my iPhone and have the same problem

Thanks for the update and for trying on both your Mac and iPhone. Since the issue happens across devices and browsers, it suggests the problem might be related to the CLT+ website or account rather than just your browser or device.

Before we explore that, let's do a couple more checks for Safari on your Mac and iPhone to rule out browser-specific glitches:

1. Disable Safari Extensions: Sometimes extensions can interfere with website forms. On your Mac Safari, go to Safari > Preferences > Extensions, and disable any active extensions. Then try entering the license plate again.

2. Clear Safari Website Data: Go to Safari > Preferences > Privacy > Manage Website Data, then remove data related to the CLT+ site if visible, or just remove all for a clean start.

3. Check that cookies are enabled: Safari needs cookies enabled to keep session info. In Safari > Preferences > Privacy, make sure "Block all cookies" is not checked.

4. On your iPhone, go to Settings > Safari and clear History and Website Data. Also, make sure "Prevent Cross-Site Tracking" is disabled temporarily.

If after these steps, the plate number still vanishes from the input fields when you proceed to payment, it’s likely an issue with how the CLT+ system handles input or session storage.

In that case, I recommend contacting CLT+ support directly at [email protected] with the details you shared here. You can mention you’ve tried multiple devices and browsers, so they can investigate the backend forms and session handling.

Let me know if you want me to walk you through any of these steps, or if you want to try a different workaround before reaching out to support!
