Sarcasm noted, but from what I can see, 1.18.1.2019 never appeared in the beta channel, last beta pushed was 1.18.2.2015, which never got as far as being available for my Shield (Play Store lag, or not dropped?) although I do have it on my backup macOS PMS server.
sigh Just came here to say that I am also experiencing the same thing. Not going to touch a thing and spend hours manually putting in metadata. Luckily I have a backup server.
Thanks for the update, but sadly it doesn’t seem to work for me. Just updated, but the plex server still doesn’t start. Restarted the shield to be sure but sadly it didn’t help
Just updated mine on the Nvidia Shield via Google Play store and all is running fine again now.
No need to reload my library, everything is as it was before.
