Similarly, as a non-European, when did the "Czech Republic" becomes "Czechia" (at least on Google Maps)?
"On 17 May 2016 the Permanent Mission of the Czech Republic to the United Nations informed the UN that the short name to be used for the country is Czechia." [1]
The official full name in English continues to be "the Czech Republic". [2]
