In the scenario explained below:
If number of days left for the for offering start date is less than threshold set at Scheduled Offering Delivery APM level and reminder emails are already triggered for the users who were enrolled before.
Then the new user registered is not getting the reminder email when the APM runs next.
Learning Management System
Once "Scheduled Offering Delivery Notification" APM sends reminder notification for an offering then it will not send any reminders again for the same offering, So if any new users register for the course after the reminder is sent then they will not get the reminder emails.
The reason for which is as the reminder emails area already triggered for the offering then the database updates the RMNDR_SENT column as "Y" for PA_SCHED table, when the APM see if the RMNDR_SENT is 'Y' it will not trigger emails for it.
