This time the app launches, but a region lock appears saying that it doesnt work in my country, with a direct link to changing addresses for google wallet.
I set it to a USA address, and a day later it let me access the app.
I set tap and pay enabled, after entering my NZ Credit card details, but a USA billing address. An NZ billing address would not work.
Once this was enabled, i gave it a shot at a local BP.
So does this work in NZ at all, or is it completely blocked, even when entering a USA address above twice like described?
