Chime will track payments, send money requests and payment reminders, and display the expense in the group’s activity. You can manually send one reminder for unpaid requests from the group page or the expense screen. Chime will also continue to automatically send payment reminders regularly via push notifications. If the expense isn’t paid, it will expire 60 days after the due date, or, if no due date was set, 60 days after it was added.
To stay updated, just make sure Chime notifications are turned on in your phone’s settings.
