Setting notifications for certain guests will let you know when they check in. To do this, open your event’s guest list. Select the guest you want to set a notification for by tapping their name. Their contact card will appear. Tap on the bell icon (Notifications) and turn ON Check-in Notifications.
A star will appear on the contact, indicating that you will be notified when this guest checks in.
***Please note if you're sending the notification to an international phone number, it requires the '+' symbol followed by the country code. For example, a Turkish number would follow the format +908001234567.
