Photon - Second Player can't play

Options
Hello there,

I'm trying to setup a simple 1v1 MP game. My Menu works just fine, i can connect to the master and i can spawn both Players. But when both players are ready and the scene is changed, only the MasterClient can play. The other player sees the new scene but the game is frozen. The MasterClient sees the other player, but can't perceive the movement. Did I forget something or do I have to pay attention to something?

(In PhotonHandler):
void OnLevelWasLoaded(int levelNum)
    {
        if (!PhotonNetwork.inRoom) return;
                CreatePlayer();
    }

private void CreatePlayer()
    {
        if (char0 == 1f)
        {
            PhotonNetwork.Instantiate(Ninja0.name, Ninja0.transform.position, Ninja0.transform.rotation, 0);
        }
}
Greetings
