"I sleep less than you."

Translation: मैं तुझसे कम सोता हूँ।

'Aapse' worked me. You had entered 'tumse'. Probably a mistake from their side because both are correct for 'you'.

Hey, this one just failed me for missing out the full stop! That's harsh, Duolingo....

You missed a word.
मैं तुमसे कम सोती हूँ। (only । was underlined....)

Can I use tumse

[CRSWoodferns]

You can!
"Aapse" is the most formal way, or a way to address someone older or more respected than you.
"Tumse" is a formal way to address someone around your age.
"Tujhse" is the least formal, used for someone who's close to you, or informally talking to someone younger than you.
You can use either of the three~
