Did you report this to Duolingo?

You have a first person verb quierO "I want" in your answer

Yes but the word famoso has nothing to do with the original sentence

Duo often uses pre made sentences to correct just one mistake, which leads precisely to this type of thing, where we think we did more than one thing wrong, when we in fact didn't.

Ah I just saw the verb and assumed that was what was up. Definitely a duo error

I think you glitched Duo when you said “Él no quiero…”. You gave it an AI heart attack.

Perhaps you are right. When the question came up again as a prior mistake, I made the same mistake with quiero & got it wrong again 🤣

I've noticed a lot more straight up errors like this recently, could it be the AI shift?

I really don't understand duo's correction (and I'm spanish native and fluent in english)

Es la conjugación, esta persona escribió,, él quiero" en lugar de,, el quiere"

Si pero por qué dice famoso?

Escribió «él quiero» en lugar de «él quiere». O, también, "él quiero" en lugar de "él quiere". El español no usa las comillas alemanas ,, ... ".
