Infuse will group content from multiple sources together in the Library. If you prefer to browse them separately, you can do so via a direct Plex favorite. You can then also exclude content from the Library by adjusting the Settings > Library page.
Bit confused here, on tvOS I have the library section show “Movies” “Anime” “TVShows” and “Other” all 4 coming from Plex which I have checked on. Could you tell me what you meant by “direct plex favorite”?
and thanks! did not know collections are limited on that aspect.
