I’m having the same issue. There is a Dateline episode in My Feed that I cannot delete. When I click on it , above the photo of the episode, there is an asterisk and it says “Not on Roku Yet”. I can’t find it in the search area either so there is no way to unfollow it and remove it. In any case, the whole premise of having to search everything in order to remove it from my feed is ludicrous. This is 2020, Roku. There is no need for such inane, primitive programming. Place an easy removal feature in my fee already!
