Deleted chats are removed from your list of chats but will reappear if there is new activity in the conversation. To delete chat messages, follow these simple steps:
If you're using an Android phone:
Delete a chat from the list of chats:
· Press and hold the chat you want to delete
· Tap the trash can icon in the upper right corner
· Tap "Delete Chat"
Delete a conversation from within the chat:
· Tap the three dots in the upper right corner of the chat
· Select "Delete Chat"
· Tap "Delete"
If you're using an iPhone:
· Tap the three dots in the upper right corner of the chat
· Tap "Delete"
· Tap "Delete" again
Please note deleting chats is final and they can't be recovered unless the other person in the conversation sends a new message.
