That is probably true. I am getting older and things that change from the familiar are becoming a bigger challenge. I used to think I was pretty computer savvy. Fortran, Basic and Visual Basic aren’t as universally used as they once were (LOL). In any event I hope my comment helps someone. I was changing out a controller and for some reason I didn’t find the process as intuitive as it should have been - probably just me. I could have been confusing the process with Amazon Echo or another device…who knows.
