In v56 of Netflix we have improved our compatibility with Netflix. Now, installing the Widevine Plugin
(Settings > Media Pugins > Widevine Content Decryption Module)
and rebooting after install is all you need to do to make CloudReady compatible with Netflix.
If you're a long-time CloudReady fan you'll know that, in the past, it was necessary to enable Widevine and reboot, but also to install an extension to change your user-agent, helping Netflix to recognize your device as capable of playback.
That extension is no longer needed as of v56, so feel free to remove it real quick before you return to Reggie Watts' excellent Netflix special.
