Yes, i have a Harmony remote also but it's so old now that Logitech isn't suppoeting it anymore.
Now I'm using the U1 and I like it.
Programming and adding items isn't a problem, what i want to do is have a function to jump to Disney+ but I'm missing something on how to do that. the way I have to access it through the TV apps but I don't see it listed in the menu to reassign one of the buttons to do that. Anyone have any ideas? Cheers.
