Hello @accounts210,
We haven't received any reports from other users who are unable to connect with American Express with QuickBooks Online (QBO) banking.
That said, let's consider logging in to your QBO account using a private or incognito window 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 for a compilation of articles you can use while working with us: Banking with QuickBooks Online.
If there's anything else that I can help you with, please let me know by leaving any comments below. I'll be here to lend a hand.
