Unity Photon cant see players when joining room

I am making a multi player game using unity with Photon networking. I already made a login screen, a lobby and a level. When I host a game I join the level and I can see other players who join later then me. But every player who joins next cant see te players already connected before him.

Unity gives the error about Photon id that are 1000 and over and that such PhotonVIew dont even exist. Is this the cause of the problem or is it something else. And how do I make this work?

Help is really appreciated and thanks in advance!

@KevinJ i also had the same problem and the problem is ** how do you load the game scene. You must had use SceneManager.LoadScene(your game scene name), but you should use PhotonNetwork.LoadLevel(your game scene name)**.

How are you creating your players? Are you using the networked instantiation? if not, you have to buffer your instantiations so that your players who join later will get the instantiations as well. Otherwise, it will send your commands to current players, but not future players. An important aspect of network programming is knowing which commands must be buffered for further players, and which are only for currently connected players.
