Well you can report it by highlighting the Channel a and pressing Star*.
it'll fix itself soon. watch something else like Pluto or Tubi.
Thanks for the post.
We would recommend manually checking for an update on your Roku device and seeing if you are still experiencing an issue.
For more information about how to check for a manual update, visit our Support page here: How do I update the software on my Roku® streaming device?
