Hi. I hooked up an Amazon firestick to my LG OLED55B6P TV, which supports Android applications, then installed IP Vanish on the fire stick and subscribed to IP Vanishe's VPN service. When I go to websites to check my IP address it hasn't changed to match the VPN IP address provided by pia. What is going on? I use a 5031NV modem provided by ATT U-verse if that matters.
