So, I have been playing the game for over 3,4 months now. There's this one consistent issue that I just found that others are facing too. Even though my connection has been stable, sometimes when the opponent leaves (as it displays the message that opponent is joining) the match, I automatically get back to my login screen where I am asked to login in again through Facebook. It's been happening for quite sometime now and it's really irritating considering that it breaks our streaks.
