Hi! I have currently created a firstperson blueprint template project and set it up for multiplayer using steam, the only difference from the default template is find/join session nodes in a widget.
I will get back with results after I’ve scrambled some game testers and investigated it. I will also compile some different builds and if the template works fine I will try migrating the game to a fresh project, trying to eliminate possibilites.
I’ll get back as soon as I can. Thanks for looking into this issue!
