Helping you open your invoices is my priority, wbailie.

At times, the collected cache files on your browser may lead to unexpected behavior like the one that you've experienced upon opening your invoices.

To get this issue sorted out, as an initial step, you can press the F5 key on your keyboard to refresh the page. If you're still getting the same result, I recommend accessing your account in a private window.

• Google Chrome: Press CTRL + Shift + N.
• Safari: Press Command + Shift + N.
• Mozilla Firefox: Press CTRL + Shift + P.

Once signed in, go back and access your invoices from there. If it rectifies the issue, go back to your main portal and clear its cache to remove the browser's history or you can press CTRL+Shift and Delete key on your keyboard altogether. You may also try accessing your account using another supported browser.
