My bank says it's updating but it doesn't

Welcome to the Community, @georgehara51.

I have just the steps you'll need to get these bank transactions updated in QuickBooks. 

To begin, try refreshing the connection while accessing QuickBooks in a private browsing window. Depending on your browser, here's how to access the incognito mode:

• Google Chrome: Ctrl + Shift + N.
• Mozilla Firefox: Ctrl + Shift + P.
• Internet Explorer: Ctrl + Shift + P.
• Safari: Command + Shift + N.

Then navigate back to QBO and sign in. Head to the Banking tab and click Update. This will force QuickBooks to initiate a fresh connection with the existing banking portal that you're using. 

In case you received other errors, you can check out this link for the troubleshooting guide: What to do if bank transactions won’t download or there's a bank error.

Also, these guides on manual upload and excluding transactions will help you in case you'll need it in the future.

Please know you can always find me here if you have other questions. Thanks for stopping by the Community, wishing you continued success.
