Is it possible to connect the Plex player App (Windows or Samsung Smart TV) to more than one server?
There doesn’t seem to be anything in the settings that covers that.
If someone already shared their server with you the libraries they gave you access to should be in the “More” section

Once you click that, you’ll see the libraries that the person shared with you. You can pin those libraries to the home screen just like you do for your own
If that’s not what you mean and you need help to get started this support article will help

Hi JaysPlex7.
Thank you for the swift response.
I don’t see anything under More >.
What I have is a userid and password with which I sign in to a server where I select the sub-account with my name and then enter a PIN.
I will read the support article and share it with the server owner to determine an alternative approach.
You cannot simultaneously sign in to multiple servers with multiple IDs.
The server owners can share their libraries with your Plex ID, Hairy_Scot.
You would then sign in using your Plex ID and see the libraries from each server shared with you and your own server if you have one.
