so i keep open my chats of the people that i talk to the most. so i noticed that one of my friends was writing me a message. and i say the little symbol for writing the message, but then sudenly the person went offline and next to their name there was a symbol. it looks like a person and to the right of the persons head there is an arrow pointing down. what does this symbol mean? I added a picture to help you understand what i mean.
