How to trigger Begin Play event on server side ?

Hello, I’m discovering networking with Unreal so I’ve followed a tutorial for first steps. I’ve made a lobby level which teleport players to game level when there is enough players connected to the session. Everything work but when the hosting player is in the game level, he can no longer receive Enhanced Input Actions events, instead he could before in the lobby. Did someone know something about that and know how to fix it ? Thank you !

EDIT : After some more researches I’ve found that it’s the “Begin Event” which is not triggered for the hosting player pawn, so the mapping context is not added. I’m trying to find a way to solve that.
