What is the expected behavior?
A movie playing

No movie starts playing and netflix eventually displays an error message: Error Code: M7063-1013

Did this work before? Yes Yesterday on Ubuntu 14.04 same chrome version

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes 

Chrome version: 50.0.2661.102  Channel: stable

Flash Version: Shockwave Flash 21.0 r0

chrome://components does not list the Widevine plugin

chrome://plugins does have the Widevine plugin enabled

Netflix support claims this is due to Chrome not supporting Widevine on Linux (it did), but apparently since Ubuntu 16.04 that no longer works.
