Hi, @Mamie2.
Greetings from the Roku Community!
We'd be happy to share further information about your content concern.
Since you've subscribed to Paramount Plus via Roku, please be informed that you have to access this app inside The Roku Channel. As we've checked, this content is not available on Paramount Plus via The Roku Channel, and it may be possible that it has already been removed (expired) as per the license agreement.
No worries! You may directly coordinate this with Paramount Plus Support for further assistance as they manage their app on the Roku streaming platform independently. This includes content available within their app.
In the meantime, the movie Cousins is available to stream via Prime Video, Apple TV, and Fandango at Home.
We hope you find this information helpful.
Best regards,
Carly
