My Samsung TV is less than 3 years old but I cant find HBO MAX in the App Store, is it unsupported? I live in Barcelona, Spain

It seems crazy that I have Netflix, YouTube, Amazon, Spotify and millions of Apps available that I have never heard of but nit HBO. Plex comes up when I search HBO, who are they?! Is HBO only for laptops in Spain? If I mirror screen from laptop its jittery and I cant download from HBO, so teh solution seems to be to downloafd illegally and play via airplay, in that case shoudl i just cancel HBO?!
