Office Depot card not showing up in passbook

I haven't tried the Office Depot app, yet, but to add the pass to Passbook, there needs to be an explicit step where you view the pass. After you explicitly add the pass to Passbook from the Office Depot app, then it should appear in Passbook.

It's only to be used with the coupons. Go into the coupons' screen and you are gonna see the option to add it on passbook.
