Check out the article below for troubleshooting Passbook, I have also included the excerpt of the troubleshooting steps.
If the pass isn't appearing on your Lock screen as expected, try these steps:
- ▪ Tap the info icon on the pass and confirm that "Show on Lock Screen" is on.
- ▪ Tap Settings > Privacy > Location Services. Make sure that Location Services and Passbook are both on. Note: Location services work best when Wi-Fi is enabled. Learn more about location services.
If the pass is appearing too frequently on the Lock screen, you can turn off that feature for a specific pass. This can be useful when you work or live near a location that uses a pass in your Passbook.
