One place you can watch the cartoon Maya and Miguel is this website KissCartoon https://kisscartoon.es/Cartoon/Maya-and-Miguel
I mean there is PBS Kids http://pbskids.org/mayaandmiguel/english/tv/index.html but not all the episodes are featured and some of the videos are not full-episodes. And not every episode featured is in English, some are in Spanish. But there are more episodes on Kiss Cartoon.
If you're a Windows 10 user, you can also watch it through the Cartoons Unlimited App (which still requires internet access.) This app only works for Windows 10 and better, not for anything under Windows 10 (I used to be able to watch it with Windows 8.1 but it couldn't be done anymore.)
So if you want to watch full episodes of Maya and Miguel, there you go! Enjoy!
