I saw it come on at around 10am on Tuesday, clicked on it and it tried to load the seat map but then just gave a message saying you're not able to buy in this area, I thought they might just be getting it ready as it was only on for around 10 minutes (I kept refreshing, it could only have been clickable around 15 minutes at most) but maybe that was it? Can't believe it would have been that short a timeframe to do it when they don't announce when it's happening though, but maybe they did that just to say they've done it, and maybe I wasn't able to move because there wasn't anything available in my section, who knows!
