I’ve gone through all the settings on my Xbox app (including the setting that’s supposed to make it remember my last used section), and nothing seems to work…
All I want is to see my own server first when I start up the Plex app, instead of Plex’s streaming services such that I have to go down to More and then select my server and then choose a channel.
Remembering positions/tabs refers to Plex remembering the last tab you had selected inside a library (e.g. recommend vs. library vs. collections vs. playlists).
Check out the option to pin/unpin/order libraries to the main navigation; if your setup is completely crazy you could even reset and re-initialize the configuration of the navigation. https://support.plex.tv/articles/customizing-the-apps/
You can adjust the visibility of Plex‘ online media sources in your account settings.
