Hello Cocoon,
Thanks for making us aware of the issue you're experiencing with TSB bank, are you using a Mac pc and getting the error when reconnecting? This issue has been escalated with the banking team. We can not offer a refund for a bank not connecting as we are a 3rd party connecting to a bank as we can not control changes that would impact our connection by the bank. You can still upload an excel spreadsheet of downloaded bank transactions into QuickBooks and add and match as you would transactions through a bank connection, more information on how to do that can be found here.
