Looking a little more deeply; trying to use Brain Cloud with the Lyra example code
https://github.com/getbraincloud/braincloud-unreal-plugin-src/blob/335e9c6fe0deb6674254b30ba5edb24f9a35817c/Source/OnlineSubsystemBrainCloud/Private/OnlineSubsystemBrainCloud.cpp#L28
The session interface isn't written (nullptr) is returned. Can I presume from this that the OnlineSubsystem is in a pretty "early access" form?
