My itinerary has 2 passengers. After using the official SingaporeAir iOS app to OLCI, when I try to get mobile BP for Wallet (formerly known as Passbook), it always, and only, generates the BP for the first passenger. Anyone encountered similar issue? And anyone found an alternative method to add a BP to Wallet? Thank you in advance.

Note: understood here is no tech support, and at least email BP seems to work, only less convenient.
