Open the Portico app and sign in with the Portico Account invited to the server. The app shows the servers available to that account.
Choose the server you want to use. On the same network, the app can prefer a verified local route. Away from home, it uses current signed connection information for the authorized server.
The server may ask for a server-scoped session before opening its libraries. Completing that step does not give the app access beyond the current server permissions.
If the account has no servers, confirm that the invitation was accepted under the same Portico Account. If the server appears offline, work through Server not found.
