The conversation between human and AI assistant.
What does each check box mean when a message is sent on messenger? How do you know when it has been read?
I see. Can you tell me more about the read receipt feature?
Sure. When a message is sent on Messenger, it is automatically marked as "seen" by the recipient when they open the chat thread and view the message. You can also manually turn off read receipts in your settings, but this means you won't be able to see if someone else has read your messages either.
