I will report here about my experience to watch Netflix as written in the title. To do so, I got a current LE image from @balbes150 (thank you). I have asked him about the different versions he offers for Le Potato:
All versions of libreElec (LE) use the common core of aarch64 (64 bits).
There is only one 32-bit library (arm) for Netflix. Therefore, I am releasing two versions of LE.
ARM version = core of aarch64 + the whole ARM system.
aarch64 = core aarch64 + whole system aarch64, this version runs 20-30 % faster than ARM.
By the way, it would be interesting to check if Netflix works on Armbian, it may be possible to run it in the environment aarch64 + 32 bit library.
So I chose this image: LibreELEC-AMLGX.arm-9.1-devel-20190604084103-a41fdf1-lepotato
After writing the image on the SDcard I had to walk through the basic configuration of LE (by the way no SSH - you must use a Display and Keyboard) you find more information here:
A german screenshot film, that guides you through the process of installing the Netflix addon from libdev + jojo + asciidisco https://youtu.be/gyue62JWEkc
Netflix addons; the Kodinerds repository is already part of LE, that saves you some time, update this first.
The update and install of the Netflix addon (libdev + jojo + asciidisco), which has some dependencies, is tricky. I had repeated this process several times and a reboot once, because it would only install a few, but not all of the 9 dependencies at once. After 4 or 5 times it confirmed: installed. Now, keep following the YouTube film mentioned above.
