After not being able to use FindSession due to an empty results array on success. I attempted to open the remote ip directly using a console command “open _WindowsServerIP_” which crashes on the first attempt after the server is started up, but works on subsequent attempts if the server is left running.

Has anyone else had this problem/is lan networking on mobile really just that broken at the moment?
