I have this same problem.
When I try to access linked accounts in BANKING > BANKING HUB, I get this message:
"Something went wrong
Try refreshing your browser
If the issue persists, contact MYOB support"
I have cleared cache and history
I have tried different browsers
I have tried different devices
i have disabled firewall
I have updated browsers
I submitted a support ticket 5 days ago.
I was then told to do all the things above, which I already told them I had done in the original support ticket.
I have sent two follow up requests and no response.
What do I do now?
