Hi there, @skessler.

I understand how this has been challenging on your end. Even after contacting both support from QuickBooks (QB) and AMEX, the bank details still don't show up. Let me share info and direct you to the best possible help.

Currently, an investigation (INV-97278) about missing bank feed details of the card user's name for AMEX is in progress. With that, we recommend contacting the QuickBooks Online (QBO) Care Team again to add you as one of the affected users. Once the update is available, you'll be notified through email.

 You might want to automatically categorize your bank transactions. Feel free to read this article: Set up bank rules to categorize online banking transactions in QuickBooks Online.

If you have additional questions about managing your bank transactions, don't hesitate to reply to this post. I'll be willing to lend a hand. Have a good one.
