I want to block a friend.
Block friend feature allows you to block friends from being added as recommended friends.
If a person who is not your friend requests a conversation, or if you do not want to chat with a friend, you can block a friend by using the 'Block Friend' function.
Only when a stranger, not a friend, initiates a conversation, select the ‘Block’ button at the top of the chat.
If you accidentally block a friend and want to chat with a blocked friend, you can cancel it by selecting "...More" at the top of the Friends tab and clicking 'Unblock' on the Manage Blocked Friends menu.
I want to delete a friend from a chat room.
If you want to delete a friend that has already been added, you can also delete it.
When the friends' list appears on the Friends tab, select the friend you want to delete and press the ‘Delete’ button.
