All my bank accounts are linked but one and i can't figure out why
Let's ensure to reconnect your bank account, @workofartjohnso.
When a bank disconnect from QuickBooks Online, the bank stays active but will not download transactions. Before reconnecting it, you’ll have to clear the browser's cache first to refresh the connection between your bank and QBO. It could be the reason why your bank account disconnect from QBO.
If it doesn't work, we can reconnect your bank by following these steps:
Go to your bank's website and enter your credentials.
Copy the bank URL.
Go to your QBO Banking page and select Add account.
Paste your bank's online banking URL, press enter, and try connecting again.
