I'm having some trouble with the text input box for the control page.
I add the "input" and then it shows up on the control page, and as a datasource. I select this datasource for the field I want this text to go in, but nothing shows up. I'm likely missing a step here, but dont know what it is!
After adding an Input control, go to a Widget and select 'Input controls' as the dataset. Then go to a label in that widget and change the data bindings. Now you should be able to select any of your input controls as the binding.
It's possible that the text will only show up on your label when you run the theme in ATVO and not in the editor, I'm not sure.
