I had the same issue initially and had to contact them here
There was some issue with a verification email not being sent correctly.
I got a quick response and it was fixed within 24 hours.
(Hasn't helped me to win any tickets yet though...)
Best - Lebanese Meze stall in Park. Delicious mix of 8-9 different dishes (Veggie & Vegan) for £11. Only found it on the Sunday afternoon but will head back in the future.
Worst - Caribbean (Delicious?) place to the left of the stage in Park. Lukewarm Goat Curry with rice for £10. Chaotic queuing system with a long wait which wasn't worth it.
Snap - must be lots of spares for those gigs, I got both as well.
It looks like 2 on mine as well - seems to be active from around 3.30.
Will have to share my phone on entry as it looks like I can't pass it over to my friend's account.
