What device you use to access that Netflix at work?

Is it phone that you also use at home? Or tablet, laptop? Or is it PC, that stays at office?

As of now, I would say if the PC stays at office, then you have to pay extra. As your primary network is home.

Anyway, just wait and see how this things goes, if we can set our phone as primary device, then you just open Netflix once every 30 days by connecting to the same network your office PC connected to, you should be safe.
