That doesn't surprise me at all. I just also know Roku has been around forever, so I trust that if a new service is added, it will be there. I don't know that I can say the same about other manufacturers (not that they _don't_, I just don't have the same level of trust there).
Eventually it should be there. For example, it took a long time for HBOMax to make it to Roku because they couldn't agree on how much of a cut of the subscription fees Roku should get.
