I'm developing a mobile multiplayer game, i've red official advise about it but they say "You can publish it with 2018.4 (LTS)" and I can't use 2018.4 version because in my project i use LWRP which is not in the 2018.X versions.
I've found the alpha version of the new system right here
My questions are:
1- Should i use the alpha version of the new system? And can i publish my game with it?
2- Should i wait for the new system came out? (I can't wait for months)
3- Should i try to use other third party systems like Photon?
Or is there any way to publish my game with nice multiplayer system?
Note: I can't pay for multiplayer matchmaking system. Because of that i want to make Hosting multiplayer game.
