Relay data sharing

Hi ! I'm trying for 3 days to share data by a relay to my chess app but it didn't work. Do someone know how to do that ?

Do you mean using Netcode for Gameobjects and the Unity Relay Service?

Yes !

Easiest way would be to save the gamestate to a Network Variable that will get synced to both players.
You could also use Cloud Code if you don't need netcode

Since its only 2 players, the host could just send the updated board state in a client RPC if you want
