I am thinking of signing up to Netflix for the first time. I have a smart TV with a Netflix button so obviously I'll access it that way. However, if I opt for the basic package (can watch on one screen at a time), can I log in on another device NOT at the same time? For context, what if I want to log in to the app via my cellphone and cast it to a friend's TV? Can I log into my account on my boyfriend's iPad? I'm NOT talking about two people/devices watching simultaneously - I mean can I log into my account on different devices? Will it think I'm still logged into my account on my smart TV?
