Guests can’t change their own reply. You can: in your RSVP overview, every row ends with a pencil and a cross.
An example. Aunt Margaret replied for two but is coming alone. Set Persons to 1, click Save and you’re done.
Click the cross. You’ll be asked Are you sure you want to remove this RSVP? Click Delete to confirm. There’s no undo.
This is most useful for duplicates. If a guest fills in the form twice, first with Maybe and later with Yes, both replies are in your list. Delete the older one; the RSVP date tells you which that is.
Next step: Close the RSVP
