Watch Netflix series offline?

Sers

I share my Netflix account with my two flatmates. Unfortunately, our account is limited to two users at the same time. Couldn't a user just download their videos in advance and watch them offline while the other two co-users are online?

You can download the films or series and then watch them offline

You can download them on your cell phone

But just look at everyone.

Unfortunately we have very different interests ^^.
