Starting a new Netflix problem thread because the previous one seems to indicate that the issue reported in that one is related to an old version of inputstream.adaptive.
With that said, I'm on a fresh install to a Raspberry Pi 3 B+ using libreelec-RPi2.arm-8.95.002. And netflix from the repo as of 1/18/19. Fresh install, boot up, add inputstream.adaptive from libreelec repo, then add netflix repo, then install netflix plugin from that repo, then I configure my user account, then finally reboot.
After rebooting, and signing in to netflix, I go to watch something and that triggers libwidevine install where it grabs the chrome image. That is where it is stuck. It says it completes, but it won't play a movie. If I reboot and try it again, it does the entire download and extract again.
Wash, rinse, repeat.
