I have set up my Echo to control my. Harmony Hub. I installed both the Harmony Skills and arrived at a situation where I didn't have to say, "Alexa, tell Harmony to pause", but just "Alexa, pause". Then, the next day, I was back to having to say the whole "tell Harmony" thing. I reset the Echo, reinstalled everything etc. Same thing. Back to the whole spiel again. The settings just aren't holding. Any ideas?
