My first suggestion is change Netflix addon, asciidiscos version is not updated regularly these days. I recommend CastagnaIT Repository for KODI 18.x LEIA - repository.castagnait-1.0.1.zip
There also a repository for Matrix.
This version is actively being developed and is the one I used in my netflix_prep script found here on the forum [HOW-TO ALL PLATFORMS]Can I use Netflix on OSMC?(post 4) - #4 by joakim_s
