When making comments about problems with Netflix, please do make mention of the specifics of the output device being used.
Oftentimes, trying with a different output device will allow proper handshaking and stream successfully using AndroidTV and Netflix.
In my experience, certain tvs, monitors and projectors fail to match the HDMI 2.0 and HDCP 2.2 specs that Netflix dictates.
Consider your entire system before indicting your Androidtv box as the root of Netflix problems.
You should work for the Trump administration with that kind of logic. The only box that people ever bring up here having Netflix issues is the Mibox. A significant percentage of them (including for me) have an issue playing Netflix. No other streaming device I've owned (Apple TV gen 2, Xbox 360, Nexus Player, Fire TV Stick) have had issues playing Netflix.
The MiBox is in a category all of it's own in terms of Netflix issues.
