Hi @marcialaw
Thanks for reaching out here in the Community!
Channels, Themes, or Screensavers can be removed at any time for a variety of different reasons. At times, our content providers may choose to remove their channel from our platform at their own request. In other cases, a channel may be removed by us if it violates our terms and conditions. We take reports of piracy or any other unlawful activity very seriously.
For more information, please see our support page here: Why is a channel no longer available on my Roku® streaming device? | Official Roku Support.
Warm regards,
Lianna
