"Blueprint Multiplayer" Video Series is teaching a lot of wrong things

It is one reason for choosing another engine. If new users cannot get relevant, correct and updated learning material, it does not matter how fantastic the engine is.

I dont think you talk about the same videos I found: https://www.unrealengine.com/en-US/b…king-tutorials are these wrong too, the switch placement? I dont recall much about game mode, instances etc. related to multiplayer ?

Where should I go and how do I get started correct understanding multiplayer?
