I'm having the same issue. I first noticed it with Starbucks App version 2.4. Like Babaganoosh said, after a purchase, the App itself would update your balance, but the Passbook card would not, despite having "Automatic Updates" turned ON in the Passbook app. The end result was that the App said you had an X balance, but Passbook said you had a Y balance. I did get it to update in ver. 2.4 by turning Automatic Updates off then on again on the back of the Passbook card.





I recently updated the app to version 2.4.1. At first the Passbook app would also not update, but I was using my original "card" in Passbook. Today, I deleted the old card from Passbook using the SHREDDER! Fun! I then added the card back into Passbook by going into the App, My Card, Tapping "Manage", then tapping Add to Passbook. I have not tried it yet to see if this version automatically updates, but I will post my findings once I get them.
