Harmony hub questions

lisaviolet thought this was worth mentioning said

We used to be able to schedule channel changes with our Cox service, but they no longer have that option.

According to everything I’ve read, I should be able to do that with a Harmony Hub, but I can’t get it to work on a schedule. I make an activity, which works, but when I set the timer, but nothing happens.

I can’t see what I’m doing wrong.
