Since you subscribe to a premium channel through a third party like Roku, your subscription is not with that channel, it is with that third party. Consequently the separate Paramount+ app does not recognize you.
You can only access Paramount+ through the provisions of that third party.
In Roku's case that means through The Roku Channel on a Roku device.
