Click on the appropriate time slot that you need the reminder for and select the ‘Reminder’ tab. Select between ‘All Day’ or ‘Custom’ and enter the details of the reminder.
When you hit ‘Save’, the reminder will appear at the top of your Calendar in the case of an ‘All Day’ reminder, and against the relevant time slot in the case of ‘Custom’ reminder.
For ‘Custom’ reminders, a reminder will pop up at the relevant time.
This feature is currently being released in phases and will be made available to all Ray users soon.
