Where can I learn to program multiplayer games in Unity?

After completing the 2D Unity course and most of the 3D Unity course, I am interested in creating a multiplayer web-based game in Unity. What courses or resources do you recommend for that?

If at all possible, I would wait for a bit as Unity are in the process of completely revamping the multiplayer stack. We don’t have any courses on this right now for that exact reason.

Thanks a lot for the information. I will take your advice
