Thanks for your reply!
Yes, multiple users, the one I’m talking about is a “normal” user (no admin rights) and has access. InfuseSync plugin is not installed (I tried before, but it stopped updating).
So the situation is as follows (on iOS): I have two TV Shows, show A and show B. In the Library tab, A shows up under “ON DECK”, but not B. B shows up under “RECENTLY ADDED”, “UNWATCHED” and "“ALL TV SHOWS”, but in either case A is not there. In the Files tab, my Jellyfin server is visible and I can navigate down and see both shows. In the Browse tab, the “On Deck” cell only reveals A, the “All TV Shows” only reveals B. (By the way, B was added later to the server than A.) I hope this is al clear
I see this both on iOS and tvOS (not surprising of course). You want me to try the plugin again?
By the way, I was thinking of starting a thread for all Jellyfin related issues and suggestions, which then perhaps could be pinned so you would have a central thread for Jellyfin users, would that help you to save time in general and/or have a better overview?
