It would show up under the messages section. Every time I've installed the app it normally takes a few days before new messages show up. I've had the Starbucks app installed for a while so bleck does show up for me.
Hmmm. My Starbucks app hasn't given me any new messages since June. Maybe it's realised that I'm not American.
If anyone has a spare code I'd appreciate it. I have the app, and have for a long time but just switched from an iPad mini to a new air 2 two day ago and while my apps moved over, the messages did not. Should have seen that coming as there were a couple others I'm now going to miss out on. Ah well, if anyone has a spare I'd appreciate it!
