Hi there, brian-x-lu.
A cache full of history and temp files can cause unexpected behaviors, such as receiving an error while updating credit card.
Let's log in to your QBO account using a private browser (incognito). This way, it confirms if the cache is the cause and to disable it from saving your browsing data.
Here's how to use private browser:
- For Google Chrome: Press Ctrl + Shift + N
- For Internet Explorer and Mozilla Firefox : Press Ctrl + Shift + P
- For Safari: Press Command + Shift + N
Once you can already update the credit card information, return to your default browser and clear the cache. Clearing it will refresh the system, and you'll be able to work again. However, if the issue persists, try using other supported browsers.
May I ask what specific bank you're using so that I can check to see if we received the same issue?
Please don't hesitate to ask if you have other questions. Thanks!
