I guess they stopped supporting it, because I had a similar case (SQ-printed BP for LH flight) where it couldn't scan... hopeful, I sent an email, to be told that they don't support it, and that in the next app update, they'll be able to credit flights based on the booking code entry. That was over a month ago, I'm still waiting for that update :P
