Only been playing about a week on Android mobile. I have experienced about six or seven random forfeits in the last two days. While watching the opposing player, not touching the screen at all, a message pops up that I have forfeited the match. It's a bit vexing when I am a couple of shots up at the time!
Internet connection is via WiFi usually. No problems with any other games, just this one.
Cheers, chris
