Recent survey data suggests women are experiencing app fatigue, tired of constantly having to come up with witty opening lines for every match.Meanwhile, potential connections were often expiring simply because life got in the way of a strict one-day timer. The change aims to take the pressure off and give matches more of a chance to turn into actual conversations.
