Help! 2013 now, does it actually work yet? Is it just me? I've changed the time up a month, up a year. Tapped the App for Passbook. It either is a blank screen or it just opens the app separate from passbook. Shut if off, turned it back on, reset the clock again...nothing. It's probably me, but I'm reading the thread here and trying each example to get more than Starbucks into Passbook, but seem to be failing. Is there another trick? Tapping my foot while crossing my toes maybe?
If definitely works, but there aren't a tremendous amount of apps that work with it. Some require you jump through a few hoops in order to have it work. Starbucks is the easiest to set up and check, assuming you don't mind a good cup of coffee.
