Myself and three other friends are in a group chat on whats app. One of our friends in that chat has become extremely distant to the point he hardly messages in the chat. Now, the rest of us message in the group chatting about daily things. Except one who doesn't reply to any messages or get involved. The baffling thing is it shows he has been online at intervals during the day but he doesn't seem to be opening the group chat to read the messages. Is there a way you can read messages in a chat without the rest receiving the two blue ticks that the person has read the message, so I was thinking it might be that my mate comes online, waits for the messages to build up, switches off his data, checks the messages offline, so it prevents us receiving the notification that he's read them?
