I need implement "player disconnected" pop-up in my game, if player disconnected during the challenge. How system.PlayerDisconnect code executed on GameSparks? it can determine if player losing connection to the internet, automatically, or only after some disconnect request?

I tried also to rely on disconnect event to make some processing, but after many tries, I gave up. 

I didn't succeed understand exactly in what conditions this event was triggered and so couldn't unfortunately rely on it (I use action script SDK).

Good luck !

I have the  same issue, did you come up with a solution?
