We can refresh the connection by disconnecting and reconnecting the account, johan6.

Whenever there are changes made with the bank, we'll also have to update it within QuickBooks. To do so, you'll want to disconnect and reconnect the bank. Just ensure that transactions left in the For Review tab are categorized for it will be deleted when disconnecting a bank. 

Let me show you how to disconnect an account: 

1. Go to the Banking or Tansactions menu. Then, select the Banking tab.
2. Select the tile for the bank account.
3. Click the pencil icon, then select Edit account info.
4. Select the Disconnect this account on save checkbox. 
5. Click Save and Close.

Then, connect the bank account as usual. If there are transactions that downloaded that already in your register, you can exclude them to avoid duplicates.
