Reminder Emails for Recurring RSVP Events

RSVP events allow you to send confirmation and reminder emails to your event registrants for each event they register for. However, if you are sharing a recurring event with RSVP enabled, the RSVP reminder emails will be sent for only the first instance of the recurring event. The reminder emails will not be sent for each instance of the recurring event.

This is because there is an assumption that users will now have the event in their calendar - and their calendar vendor will remind them accordingly. If you want all of the events to have functional RSVP reminders, you'll have to create X number of individual events with RSVP enabled and have your users RSVP for each event.
