I’m still at a loss on this, I stripped everything down to just a playercontroller that creates a black UMG screen on BeginPlay, and disappears after 2 seconds. It works fine on the server, but on the client there is a flicker of the map before the UMG is loaded. I also did this on an empty map, empty GameMode (except changing to my TestPlayercontroller). I also tried not using UMG and having a level sequence auto play that just fades out, there is still a flicker of the map before the level sequence starts.
Any thoughts? How do I get a UMG to load before any camera shows the map after a client connects through Join Session? I’m willing to try any ideas right now
