Also you have totally miss-understanding what @secondfalseiteration was talking about.
The point is that we are now paying 30% tax to AU if our customer is from Australia on Marketplaces and that was no there until recently (this year I think) BUT we are paying 30% on Elements from first day (I am paying from 2018 - then I have start) - how that is possible?
