"राज अमेरिका से आ रहा है ।"

Translation: Raj is coming from America.

I accidentally tapped आज instead of आ and it was accepted, without even saying 'you have a typo' as it sometimes does. I don't think that's right, unless it means something else that does work, as well as 'today'?

That sounds like a mistake to me. If you see it again you can report it to Duolingo
