Mine wasn't activated either. Had a card for the same seat since they first came out.. it was a shambles trying to sort it, the one guy who,eventually let me in said he had 300 and there were at least 50 still in his queue. All around the ground there must have been thousands. Poor leadership trying to sort it. Outside B they kept us waiting for 20 mins as the handheld devices weren't working. We were then told the cards would work in K, so walked around there and no luck. Then had to queue again for about 30 minutes when I eventually got to the front of the queue took my card off me and let me in manually... Poor start to the day, good job we had a good finish..
