Samba TV is a completely free opt-in service available on apps that come with your Smart TV. As such, we'd like to help more with your question, but Samba TV does not control adding additional apps and/or channels to your Smart TV.
Because instructions and capabilities can differ depending on your Smart TV model, we recommend you reach out to your TV manufacturer's support channel or number for more guidance. Additionally, your TV model’s online user manual will better be able to assist you with managing its apps.
