To check whether your +1 is included on a Partiful event, open the RSVP panel on the event page. Your +1(s) will appear there, and on the guest list under your name.
Open the event.
Tap your RSVP status (e.g., “Going” with the thumbs up emoji icon).
Review the +1s listed under your RSVP.
To change/remove a +1, open your RSVP panel again and tap the trash can icon next to your plus one’s name. You’ll be able to select a new plus one(s).
