Hello again. So I watched your vid and all. And I can say that I there was nothing wrong with my project setup. Everything I did was slam bang correct.
So after bashing my head against a wall for a few hours, I discovered this most ridiculous (bug?) thing since I started using UE4.
Basically if I use UMG to trigger my create/find/join session events, it would fail instantly. However if I bind all these events to Android back, android volume up/down buttons, IT WOULD WORK NO PROBLEM!!!
So I am now able to use my phone to join a session created on windows. But only if I use android phone buttons to do so (otherwise create/find/join session nodes return failed results instantly).
Now I don’t know what a hell is going on here, but if I use android buttons everything works fine!!!
So I am reinstalling Unreal Engine 4, because this is beyond stupid.
Thanks mhnoni for all your help. And for epic staff who answered every thread on this subforum except mine-thank you not so much.
my pleasure .
