If they have multi-room then they need to activate Sky Go Extra online, if not they need to pay an extra £5 a month. Either way it will mean you can link 4 devices to it instead of the usual 2.
They must already have that then as I noticed there are 4 devices when I log in - my brother must have started using it though which is why it didn't let me do it.
Ah well - I can deactivate the laptop in a couple of weeks and just watch the playoffs on PS4 from there then decide what to do next year.
Hopefully the app is good on the PS4. NHL Gamecenter Live is great but wasn't as impressed with SkyGo on the laptop. Should look a lot better on the TV via PS4 though.
