Spanish language in YouTube app FIX
If anyone else has issues changing Spanish to English on your YouTube app, fortunately for you, I have quite a few skills in the Spanish language. To change your language:
For PC:
1) Click on your profile pic on YouTube and hit the "Idioma" button.
2) Pick English
For your phone:
1) Go to the smartphone browser version of YouTube and click on your profile pic.
2) Go to "Configuratcion"
3) Click on "Cuenta"
4) Go to "Idioma" and choose English.
I hope this helps you, if none of these methods work and you're still struggling then try changing your app or language settings on your smartphone, most of the time it works.
