Can't find the session using steam

Hi everyone.
For about 2 weeks struggling with this problem. Doing everything according to instructions A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums to connect steam to my project successfully connects upon startup, but the friend can’t find my session. Also I can’t find it session.
I downloaded the ShooterGame project from the launcher and everything works fine.
Also downloaded a test project from here No Find Session Results STEAM Online - Platform & Builds - Unreal Engine Forums
but it’s not working.
Please tell me why you do not see your session?

You aware of fact that you need to create a session first?

On your TestSteam.Build.cs add this:

DynamicallyLoadedModuleNames.Add("OnlineSubsystemSteam");

Yes, of course.

my delegates not even working after searching what gives?
