Thank you for your response, leonieyoung06. 

There seems to be a change in provider name from Credit Union Australia to Great Southern Bank as well as website login change, therefore leading to this connection issue. Our engineers are aware of this issue and working on a fix. I would recommend contacting our support team to have your account added on affected list for INV-72419 and receive regular updates. 

Feel free to drop a comment below if you have any other questions.
