Change or cancel your RSVP

Switch to Maybe, leave an activity or clear a request.

Open the activity and tap your RSVP. From there you can switch between Going and Maybe or remove the RSVP entirely.

Leaving removes you from the group chat, and the chat notes that you left.
If you claimed something on the bring list, leaving releases it so someone else can pick it up.
Withdrawing a join request works from the same place, and you can request again later.
