"Ultimamente não."

Translation: Not lately.

Could this be Lately No as well?

Right, that answer should be accepted. I would also argue that lately not is not even grammatically correct but that's just the teacher in me. Make sure you report this!

Both ´lately no´, and ´lately not´ don´t sound right at all. Duolingo´s translation of putting ´not lately´ seems to be the best option.
