Each channel creates, provides, and maintains its own app to stream their channel to the Roku, as well as deciding and programming its features. Roku only provides the platform on which the 3rd party channel apps run. You should direct your questions and concerns to the channel. (Exceptions are the two channels provided by Roku, The Roku Channel and Roku Media Player. For these you should contact Roku.)
