To answer your older question, when choosing a VPN provider always do your research. If the VPN is based in any of 14 eyes countries, like USA, UK, AU, and so on, they are not safe. For example, if you did something illegal while using one of these VPNs and the authorities requested information about you from the VPN provider, they WOULD NEED to cooperate and give up your activity data. In this particular case Nord is fine because they are located in Panama (which is not an enemy of the internet).
I use nord on android and it works just fine. Not sure on chromebooks, never tried it.
With the coupon that I provider earlier in the thread, I paid exactly $107.55 for a 3-year resubscription.
