Cable box Alexa Smart Soundbar300
Alexa works to control volume on TV and when asking weather, etc., but will not save the cable box model and brand that I enter on the app. When I go back and try again, nothing happens when attempting to click the Add cable box button. I tried long holding it and nothing works. I would like to control my Fios One box and be able to change channel by voice. I have uninstalled app and reinstalled. I also tried installing app on my wife's phone and it will not work.
Arris is the set top box brand
IPC4100 is the model
Any help is appreciated! Thanks.
