Fire TV Stick 2 Plex-Servers?

Server Version#: 1.28.0.5999
Player Version#: current one from Appstore

I have 2 Plex Servers (2 NAS) in my network to avoid that kids have access to content which isnt made for them. In the kids room, they have access to the child section (NAS 1). At the living room I have access to content which isnt for kids like films and series with FSK 18 (NAS 2).

Now I would like to switch or if possible to combine between these 2 Plex-Servers but I don’t understand how. At the moment I always do a reinstall of the Plex Player at the Firestick. But this is really time wasting.

Hope you can help!

You can share all the libraries from the kids server (NAS 1) to the account you use for the living room. (NAS 2) just like you would if you were sharing your home library with a friend in another location
.
Then all the libraries in the living room will show for both servers in the sidebar on the left. You can pin what you want from either without having to sign in and out

You could have also restricted the kids access as home users to the original account but you’ve gone down the road of creating the other server already. If you want to get away from that you can look at this link too

If you move all the content of the kids server to the main server, you can keep it in separate directories and then re-create the libraries from the kids server on the main one, and you can edit the exiting libraries if you wish to add the new media to the existing libraries. Then if the kids are on their own Plex account (or a managed user profile), only give them access to their special libraries. You can keep these libraries unpinned and out of mind on your own profile/account and you will still have access to the media on your own normal libraries, which now include that content as well.
