Advanced Sessions Plugin

Is there an elegant way to pass the ExtraSessionSettings over to clients? Or to request newer information from the client to its session (without refinding sessions)? The situation is, I have one client tell the server to change its game session extra settings, then I want all clients to get that information. I’ve tried passing an array of SessionPropertyKeyPair structs to an OnUpdate client RPC call but the information doesn’t appear to replicate; an array of 3 elements arrives on the client RPC but it’s all None/0/null data.
