I have the app configured in Spanish but I don’t know why the names of the species appear in English while for example settings, projects, guides appear in my native language. As you can see in the screenshot, the animals are in English but the rest is in Spanish.
I’ve just finished identifying some observations. While I was doing so, the names of the animals were in English, but when I go to ‘my identifications’ I see some of the names in Spanish and some in English.
Some names appear in english instead of spanish probably because those subspecies doesn’t have a common name in spanish. The species does have common names, but there is regular that subspecies does not at least in spanish.
