Thanks for reaching out to us, MICHELLET20.

We can update your Bank Feeds if you're using the QuickBooks Desktop. This helps to bring in those Amex transactions to QuickBooks. Here's how to update it:

1. Go to your Bank Feeds.
2. Select the tile for the affected Amex account.
3. Click on the Refresh Account button.

You'll want to check this article about downloading bank feed transactions.

If you're using the QuickBooks Online, I'd suggest contacting our Customer Support Team. We have a new case about Amex transactions that aren't downloading. 

To reach out to them:

1. Go to Help and click on Contact us.
2. Enter American Express transactions as the topic. Click on Let's talk.
3. Choose either Start a message or Get a callback.

By contacting them, you'll be added on the list of affected users. That would help our engineers to gather more details about this issue for a faster resolution.

Please let me know if you have other questions about bank transactions.
