Setup gl-axt-1800 with express vpn for miami

I was able to connect my router to express vpn and downloaded the miami.ovpn file. However when I visit What Is My IP Address - See Your Public Address - IPv4 & IPv6 I still see that i’m in south america.

How can I make this work so that all my devices that connect to the router can look as if they are in Miami?

hi,
Is the public IP shown on https://whatismyipaddress.com/ when VPN enabled the same as VPN disabled?Where does the IP located depend on the VPN server.
