How do I Fix my multiplayer?

I pretty much just wrote the stuff from the top down multiplayer game example but now, on the peer end, he can see the host move, however, when the host moves, he moves and when the peer moves, he is lagged/teleported back to the same spot relevant to the host. On the host end both characters move the same, and the host doesn't see the peer lagging back into place. Any ideas on what i did wrong?

Hard to help without seeing your code.

It might be due to the host syncing the peer's position. In the official examples the host moves the peer. So the peer will always update its position according to the host's game state. If you try to move on the peer directly, the peer will be synced back to the position of the host's game state. Peers only send their inputs, then the host moves the peer.
