Virtual Joystick multiplayer problems

Hello. I’m working on multiplayer android project. The problem is that virtual joystick of all clients send events to client #1. I saw such problems since UE4.14 even with example (template) projects. How to solve this problem?

The problem was gone when i released game (built dedicated server + no-editor client)

in my case yhe problem still exist,
any idea how to fix it?
