When you invite others to join a room booking you've made, you can easily see whether they've accepted your invitation, declined your invitation, or haven't yet responded to your invitation. To check the status of invitees on a particular booking:
Tap the More icon (rightmost tab)
Tap the specific room booking for which you'd like to view the status of invitees
iOS only: Scroll to the 'Invitees' section, and tap the > icon
Here, you'll see the status of the invitees. There are three possible categories: Attending (green), Not Attending (red), and No Response (grey). On Android these are denoted by a colored circle in the bottom corner of the user avatars.
