Why are users being able to access libraries/server that aren't being share with them?

Interesting. You can help me and a fella out on our mysterious non Plex problem with a TIP or lead us to a support article about this topic then. It can’t possibly be a Plex issue but rather something with Roku. Any insight? And btw I READ the app updates and this issue, I mean perfect feature of Plex, wasn’t indicated on any bullet points. Care to share your wisdom?
