Something's not quite right Hmm. It looks like your access has been changed. That's the error message when I pull out a customer card

Hello @grace-geneguin-r,

In QuickBooks Online, the frequently accessed page resources stored on your browser may affect your browsing experience. They can cause unexpected browser problems like what you received while trying to pull up your customers' payment information.

Let's consider logging in to your QBO account using a private or incognito browser so we can isolate this issue. To do so:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P

If this works, you can clear your regular browser's cache so the system can start fresh. But if you get the same results while using a private browser, use a different browser app instead.

Additionally, I've also included this reference helpful with a compilation of articles you can use while working with us: Browse all articles for your QuickBooks product.

Don't hesitate to post again here if you have other questions or concerns with QuickBooks tasks and navigations. I'm always around happy to help. Stay safe and have a good one!
