Welcome to the Roku Community, 6255!
Thanks for reaching out. We'd be happy to provide further information regarding this matter.
Firstly, may we know how are subscribed to this app? Are you billed via Roku or directly from the service provider?
If you subscribe directly to this app, we highly recommend coordinating with the channel provider. Roku doesn't manage channel logins or authentication, and many Roku channels are developed and maintained by the channel providers themselves.

We hope you find this information helpful.
Warm regards,
Carly
