I called Amex australia international MR team and they said US knocked it back . I had transferred to the US from my Uk MR account I’m 2020 and they said my US account can receive only once a year .It’s once every 12 months, not calendar year. And I did it recently. 99% of CSO’s have no clue about this, so don’t worry too much on what they say. Keep trying until you get someone who can do it.
