Hi GEB​
This decision by MYOB is going to prove disastrous for many users. If nothing else, I would suggest you advise your clients with offline files to 'STOP' MYOB's monthly updates. If not sure how, get in touch with FGH Tables, they can stop the updates. This may only be a temp solution, but it will buy some time at this critical stage of the financial year.
Stopping updates will also mean tax table updates might not be available, however if your clients are offline and use payroll, they likely already have other payroll related solutions.
