1) What happened
When creating a Scoreloop Social client from the BlackBerry plugin, the game crashes always on a real device. However, within the Unity Editor, everything appears to be working fine.
This has not always been the case, a couple of moths ago, the plugin was working as it should.

2) How can we reproduce it using the example you attached
Just build and install it on a real BlackBerry device. The game will crash when authenticating.
