I can help you sort this out, @Hernando.

Let's first access your account using a private or an incognito browser. This helps us isolate the error for a possible browser-related. You can use any of these keyboard shortcuts:

• Ctrl+ Shift + N for Google Chrome  
• Ctrl + Shift + P for Mozilla Firefox  and Microsoft Edge  
• Command + Shift + N for Safari  

Once logged in, you can try accessing your customer's invoice again. If you can no longer see the error, you may want to clear the cache of your regular browser. Also, you can try using a other supported web browser to further isolate the issue.

If the issue persists, I'd recommend contacting our Customer Care team. A specialist can further look into the error and determine its root cause and resolution. Here's how:

1. Go to Help menu (?).
2. Select Contact Us.
3. Enter your concern, then select Let's talk.
4. Choose a way to connect with us:
   • Start a chat with a support expert.
   • Get a callback from the next available expert.
