Again - that was probably one of my luckiest trips about 2 weeks ago. Got op-upped before OLCI on the outbound and again about 3 hours (after OLCI and downloading my BP to the app) before departure on the return.

For the OP - you can refresh your boarding pass on IOS and Android apps easily - it will update if you get an Op-Up - although you might end up with some interesting words on it - like it saying '1A - World Traveller Plus' for example.
