Hello Tuwilliger,
If your bank balance shows £0.00 after connecting to your bank account in QuickBooks, sign out and sign in again to QuickBooks. Then, you should see the correct bank balance. If not, select the Update button to try again. If it still doesn't show your balance then if you can try to clear cache and cookies or try logging into QuickBooks see if the balance shows if not try login in an incognito / a private window. One of these should show the balance show up for you.
Let us know how you get on.
