I can't see anyone on this page that has been abusive. Everyone is just expressing understandable frustration at software that isn't working, that we are paying a lot of money for, and asking for updates on, that aren't forthcoming, hence leading to further frustration. And as we don't have direct access to 'the overlords' in the USA, the only voice that can advocate to them on our behalf is whoever is handling the Australian MYOB queries, like the moderator on this page.
I am glad you got yours sorted, that is a definite plus for you. For other people the whole ATO myID portal and the Relationship Authorisation Manager (RAM) authority etc is not an option, for me personally, my Father doesn't trust anyone with that much personal information, they want you to upload drivers licenses/passports, birth certificates, Medicare cards, my 76 year old Father just moved, he has no idea where his birth certificate is to even begin this kind of set up in time to lodge May IAS. It is just frustrating and the lack of updates even more so. Well done on your win.
