I noticed that the main search bar for Plex servers, fails to provide search results for media outside of my libraries, in the wider Plex network ecosystem.
By comparison, searching for books in the Kindle search bar matches both in-library results, as well as wider Kindle store results.
There isn’t an option for the wider Plex network in the search settings Sources to Search UI.
This introduces friction for discovering the vast majority of content.
Note: Searching rental options is not available to managed users; nor is more ways to watch. And none of the discover options can be enabled for managed users (in the online media sources settings).
