When a supporter RSVPs to an event we now show them a confirmation screen that includes a variety of "Add to calendar" buttons for all the most popular apps. The buttons allow them to add the event to their favorite calendar with all the event details attached and including a set 1 day before reminder!
If the supporter has assigned themselves to any shifts, we will show the shifts' details in the event description.
We are planning on introducing the "Add to calendar" buttons to other RSVP communications soon!
