I followed the request to update widevine (and did not backup in advance). But the update has not been successful. I breaks down. Meanwhile I have spent much of my remaining livetime, but no success. Last attempt was via Netflix. My environment is as follows:
raspi 3+
libreelec 10.0.4
kodi 19.5 Matrix
I have uploaded an extended log : https://paste.kodi.tv/owadixagik
Disney+ runs with its own loaded widevine, but my preferred Amazon VOD and Netflix as well as other -Streaming Addons refuse.
I am sticked in a depression just before Christmas. No fun. A Dino would be glad if somebody could serve as St. Claus.
