How to turn the First Person c++ template into multiplayer

I was watching these tutorial series on making a multiplayer game (Unreal Engine C++ Multiplayer Survival Series #2: "Creating hunger/thirst" - YouTube). This guy was using the Third Person template (c++), but I wanted to use the first person and I haven’t tested it with the third person template. What I did was creating a new project with the First Person C++ template, adding multiple network spawn points, and increasing the player amount to 2 in the dropdown beside the play button. I tried it with a dedicated server too and got the same result. Both clients spawned at the same point, and couldn’t see each other. Any reason this might be? I checked and in the character class in the constructor SetIsReplicated(true) is called.
