Please urge them to remove it or relocate it. If you want search to be a click away from Home then put it immediately above or below home on the left side menu bar.
Putting it into the channel grid, and then inserting it in such a way that you are forced to navigate through it before you can access any channels is inconvenient and shows a real lack of thought on the part of UX development as to how people use their Roku devices.
As I said in the first sentence if the developers wanted search to be one click from home, just make it adjacent to home on the left. You navigate directly from the search results to the relevant channel(s) so there is no advantage to having it integrated into the channel grid. Don't make it an extra step...an obstacle really...between home and the actual channels.
I have deliberately arranged my channels by how much I view them. Now Roku has inserted a feature I almost never use between where I begin and where I want to go first.
