You disabled it? Go to Bank Transactions>Chart of Accounts>Over on the right there’s a small gear icon for your chart of account settings, click on this. As you scroll down those settings you’ll see Show Inactive, check the box. If you see your account listed, make it active. If not, call support, they have a tool that can see if you still have a live bank connection. Not sure if you ever clicked to disconnect or if there were any errors you encountered that caused your issue. Hope this helps!
