I have a Harmony Elite Hub and Roku Ultra that had been working fine until recently. I noticed that when I am on the Harmony activity I have called Watch Roku, many of the Roku channels are no longer there on the remote, just numbers. Some icons are still there. In checking further, it appears that the Harmony Hub no longer knows which channels are on my Roku. If I edit the Roku channels directly, the iOS app no longer knows about my Roku channels, which was not. Problem in the past.
