I appreciate your effort in linking your bank account with QuickBooks Online, Kim.
Once you've done it successfully, the Banking page downloads up 90 days worth of transactions. Let's do some troubleshooting steps to get rid of any cache-related issues.
Let's try accessing your QuickBooks Online account through a private browser or a different one. If the Banking page works properly, we might want to clear the cache storage of your regular browser.
Otherwise, I'd recommend reaching out to our QuickBooks Customer Care Team. They'll be able to review your account and investigate this issue further.
Feel free to reply if you have other concerns.
