New X1. Programming Roku Express. When the device is created, only a couple keys work (ok, back). Went in and programmed the other keys under device/edit/assign keys for X1. The keys work in there when 'triggered' and seem to get assigned (the orange circles disappear). But when I go back to the device, none of those keys work on the app. And, syncing to the remote, the keys don't work there either. So, what's wrong.
