Thanks Joanne

Hello,
I'm trying to integrate BrainCloud 5 with Unreal 5.3.1 but the BClient plugin fails to build.
It seems that the BCClient code is trying to instanciate protected constructor (from FUniqueNetIdString class) but can't because of the accessibility level (protected constructor in the base class).

Example:
OnlineIdentityIntefaceBrainCloud.cpp:70:
TriggerOnLoginCompletedDelegates(LocalUserNum, fase, FUniqueNetIdString(), ErrorStr);
FUniqueNetIdString() is inacessible here due to it's protected level.

Do you have an update somewhere?

thanks.
