We're excited to let you know that this feature request has been completed! Today we released an update to our calendar so that recurring appointments now include an icon to indicate that the appointment is a part of a recurring series. This icon is the same clock icon used on the client Appointments grid.
This is the first of a few releases we have planned to improve our calendar feature. Be on the lookout for more updates and if you have any questions or feedback, feel free to reach out to our support team at support@theranest.com.
