Hi Rebecca, that error usually occurs when your bank needs extra verification, such as an OTP or security questions, beyond your normal login. The Fix Now button often doesn’t fully handle those manual steps or any stuck data in your browser.
That’s also why your previously linked account isn’t updating. The connection is paused until those bank verifications are cleared and refreshed.
To fix it, start by logging in directly to your bank’s website and responding to any alerts, OTPs, or security prompts. Then, go back to QuickBooks Online, open the Bank transactions tab, click the Pencil icon on the tile for the affected account, choose Edit sign-in info, and re-enter your online banking credentials exactly as you use them on the bank’s site.
