Absolutely horrendous, I was in the waiting room 13 minutes ahead of sale time, got queued with 170ish people in front of me, no problem. My number came up, picked out tickets, hit next, kept getting the message "can't complete on this device, please make sure you're signed in to your account and come back" I WAS IN YOUR STUPID APP, LOGGED IN! Had to switch devices and now I'm 1165 in line! TICKETMASTER APP SUCKS!
