@jason Hadn't heard anything, so today I randomly unpacked the remotes from their boxes and tried the current beta (0.9.954), and export works, it does what it should, produces a have a file for the remote, and the app doesn't crash anymore.
Hopefully this was a planned changed, but seeing things have been quite here, I don't for sure if this is intentional fix or accidental, or even something MS fixed!
But providing feedback, just so you are aware something has changed for the better.
