I've been looking at this sample project here:
https://github.com/southworks/playfab-samples/tree/master/multiplayer-tic-tac-toe
It makes a note that: "Polling state of the game from the SGD is not recommended for production, as it could end up being too expensive."
I noticed that the sample project polls every 1 second. So what is the proper method I should be using to handle this?
