Update button in the banking page does not update my US Dollar account, nor can I see the Account I want to connect to in the list of my accounts with my bank.

Hi there, @globlocon.

I'm here to help you bring your banking transactions to QuickBooks Online. I'd like to know if you've encountered any errors when updating your bank account so that I can provide you the best resolution. You can let me know about it in the comment section.

For now, you can manually upload your transactions to QuickBooks. This is done to match, categorize, and reconcile your transactions. Here's how: 

1. Go to your bank's website.
2. Filter the date from the last time you've go,t updated bank transactions in QuickBooks.
3. Download the transactions using the .CSV file. (You can also convert if in the Excel spreadsheet to .CSV file)
4. Go back to the Banking page in QuickBooks Online and upload the file.

Also, regarding the bank you'd like to add to the list of your bank accounts, is it integrated with QuickBooks? If yes, you can go to the website of your financial institution and copy the link. Then, go back to QuickBooks and paste the URL of your bank. If you're able to locate the bank after that, you may follow the on-screen instructions to successfully link your bank account.

However, if you're not able to see the bank after pasting the URL, you can request support from your bank to integrate with QuickBooks. While waiting you can manually upload the transactions from your bank using .CSV file format. Please check Step 4 above to see the link on how to upload it. This is how it looks like:
