Well that's another fucked thing I've noticed Netflix seems to prefer windows. I get those login from different computer when I'm on mint I get those notices but not on windows 10, I've also noticed that I have to manually select 1080 in windows if i'm not using edge .
Come to think of it, I can't remember the last time I used any of my Linux machines to watch Netflix; usually I'm using the Roku, PS3 or my Android tablet (and if I happen to be booted to MSWin, it's only for long enough to run some specific task, I won;t be kicking back to watch videos). Crunchyroll runs fine under Linux, but their systems are so far behind the curve I'd expect them to the the last streaming service to support IPv6 (not because they hate it, but because their technical expertise is lacking).
