Multi-person chats are group-like chat rooms created by inviting friends to a 1-on-1 chat.
With normal groups, a user that was invited cannot participate in the group unless they select Join. However, with multi-person chat rooms, you can immediately start chatting with friends who were invited.
Multi-person chats easily allow you to communicate with a number of friends; however, features found in 1-on-1 and group chats (such as Notes and Albums) cannot be used.
If you’d like to share things like information and photos with friends in a multi-person chat room, we suggest making a group out of that multi-person chat.
