To add to @renojim's reply...
How did you make this "independent of Roku" subscription? Directly with that channel on its website, or through some other service third party service like Amazon, Google, Apple, etc.?
In many cases, subscriptions obtained through 3rd party services can only be accessed via that 3rd party's platform.
In general, if you want to be able to view a paid subscription on multiple platforms you should subscribe directly with that service. You'll then be able to log in on any supported platform with the credentials from your channel-direct subscription,
