Hi,
PhotonNetworkGetNextRoomProperties: that's my fault sorry. It's because I named that action wrongly when I started this and then corrected it, so you get this error. Simply replace in the states where you had implemented PhotonGetNextRoom and use the new one: PhotonNetworkGetNextRoomProperties
As for the orange warning: true, I need to remove that if you are not publishing for mobiles, the problem is that on mobile socket connection is only available for pro. Let me correct this warning so that it doesn't appears on Unity Indie if you are not publishing for mobile platforms.
bye,
Jean
