I had one browser tab open, and left it to refresh every 20 sec. I got in after 23mins. I think it was just dumb luck. I am aware of other that had multiple devices and browsers open and didn't get a sniff ??♂️
Single tab (Chrome), on a MacBook Air. Got the holding page immediately, and after 20mins the ticket page loaded and I bagged my tickets. Didn't even manually refresh and let the 20 sec timer do it for me.
