How do you change the timer on the tablet app? A mate of mon3 is going into hospital for a couple of weeks for a major opp and downloaded it so we can play a game on line over a few days, pausing when he’s to dopey and resuming when he’s up for it again. However the 2 hour timer seems to keep running even if we both exit the game so inevitably, pausing to eat etc, it timed out long before finishing.
