Without context we don't know if it means: "come in" or "go in". I tried "go in" and it was rejected. I reported it.
If I write "Puoi entrare?" does that mean can you enter?
Are modal verbs really any different than what we've studied? Why do they have their own category so far down the line?
Come in is correct too!!
Puoi is for singular or for plural?
Puoi is the conjugation for tu, you in the singular form. The plural is voi, which is like saying you (all), and that would be potete.
'Come in' not accepted Dec 2019.
The audio sonds li "poi" which should also be acccepted
