You can select any of your Mutuals to crush, and they'll receive a notification that someone crushed them. They won't be told who crushed them, but the notification will show the last event you attended together. If they crush you back, you'll both get a notification that it's a match, and they'll be told you crushed them. You can crush up to 10 people per month.
Not interested in hearing if someone has a crush on you? You can turn off Crush notifications by navigating to your Profile, clicking the gear icon at the top right to open Settings, and then tapping on the Notifications section. If you don't see this option, please update your app to the latest version.
