@2katlloyd-
If you subscribed through Roku on one TV, the subscription is tied to the Roku account (identified by the email address linked to that Roku account) to which that TV is linked.
Are the other tvs linked to that same Roku account (i.e.Settings/System/Account shows the same email address)?
