UPDATE 10/15/16: The latest update caused all of my cards to disappear. Out of desperation, I started to reload all of my cards. After the 3rd card, the remainder of my loyalty cards reappeared. So, for other users who lost their cards as well, take a few minutes to reload 3 cards and see if your others reappear as well. This update was a bust.
Just about every store has a loyalty card now, and the number of cards you have to carry around if you dont want to always have to publicly announce your phone number to anyone within hearing distance means your wallet is bursting at the seams. Ive been using this app for about 6 or 7 months now and its one of the best and most used apps on my phone. LOVE IT!!! The only issue Ive had is when youre a "fast user"...you have to give the app enough time to open and then get to the screen where you can use your fingerprint scan to log in. If you try to do it too quickly it can freeze up your phone. But, if I just remember to not be Speedy Gonzalez, slow down an extra second or two, then Ill have no issues. Do yourself and your wallet a favor and start using this app now. Very easy to upload any and all cards. Very convenient since Passbook works for such few cards right now.
