I use Kodi 18 Alfa, but I can't get Netflix plugin working, I can only get audio and subtitles working, but no video. Has someone succeeded with Netflix on Mi Box?

 I got it to work.  These were the steps I took:
1. Download and install latest Kodi 18 nightly: http://mirrors.kodi.tv/nightlies/android/arm/master/
2. Download Netflix Addon: https://github.com/asciidisco/plugin.video.netflix (direct link to zip: https://github.com/kodinerds/repo/raw/ma...-1.0.1.zip)
3. In Kodi enable Inputstream: @Karellen- LInk removed
4. Install Netflix Addon thru Kodi

And it just worked with Mi Box (but did not work with my android tablet)
The best part is that now I can get 5.1 audio out of Netflix even though I only have DD capable amplifier.

There is something weird going on with that plugin when it comes to Android:

What Mi BOX model you have MDZ-16-AB or MDZ-19-AA or other  (on bottom of box)?

MDZ-19-AA have widevine L3  (and therefore netflix mobile app works, but I can't get kodi netflix plugin working) 
MDZ-16-AB have widevine L1
