Hi there, sales125.
We can the basic-browser troubleshooting steps, and you can try to disconnect your bank account later.
To start, please open a private browser and sign in to QuickBooks. This stops your cache from saving new data and works like you're opening your browser in a fresh state. If you can unlink your bank account, you can go back to your regular browser and clear its cache. If not, please try other browsers to isolate the case.
If you still can't unlink your account after doing the steps above, please provide more details about the issue.
- the error or prompt you're getting
- the name of the financial institution
- a screenshot if possible
We'll be here to continue to help you disconnect your account.
