I used to have an AMEX connection with my dutch card through the europian union connection but that doesn't work. Quickbooks support is ***** and they haven't fixed it.

I understand that you need to regain the usual connection in Amex to QuickBooks Online, @sammyspijkerman-. Let me share more details on how we can fix this.

I appreciate that you contacted our Care Support team, and I would have thought that could be quick to fix. The Amex bank may have any system maintenance. That is one of the reasons why we experience connection issues.

Also, we can manually update your banking tab to refresh the connection and help resolve this error.

1. Go to the Banking tab and select Banking.
2. Click the Update button.

I know that you have reached our Care Support team already. If you're still experiencing this issue after the manual update, I suggest reaching out to them again. This way, they can further investigate this with our engineers. They can also check if there are updates about the hurdle since you opened a ticket to one of our agents. 

Alternatively, you can manually upload transactions into QuickBooks Online. Here's what to do if you see a bank error or bank transactions won’t download.

Please place a comment again if you have more questions about Amex and QuickBooks banking. I'm always here to lend a hand. Wishing you all the best and stay safe!
