still a good quiz though ^^
Fixed the answers not showing as well!
São Paulo, Rio de Janeiro, Belo Horizonte*, Porto Alegre, Brasília, Recife, Fortaleza, Salvador and Curitiba.
But I don't now the 10th. I think is Campinas, with 3.263.091 habitants in 2020, but not accept.
Long way to level 58
Also, there are four.
You should fill in Johannesburg/ Pretoria
