The audio menu
Every anime page states the original language, Japanese, and the service you open with Watch now carries the tracks: the Japanese original with subtitles, and the English dub, which for the kids TV shows and the long shonen of the 2000s is often the one people grew up with. Switch in the player's audio menu and the subtitles follow.
Latino and Spanish dubs
"xd anime latino" comes from a Spanish-language namesake, and the Latin American Spanish dubs of Pokémon, Dragon Ball Z, Detective Conan and the rest are on the services in those countries; set the country menu to Mexico and the Watch now list shows them.
Subtitles that will not show
Open the player's subtitle menu and choose a language; if a track is listed and nothing appears, reset the size and colour in the service's accessibility settings. The quality page covers the picture.
