How are changes in Velocity handled over a Network?

I made a DoubleJump function fora game that I’m working on, and it works, but only on the Server. When I try to call it on the client, nothing happens. Is it because UE4 is automatically correcting the velocity change for some odd reason?

Are you replicating the function?

I have this same problem. how would you go about replicating the function?
