What is left on read snapchat?

Left on read Snapchat is a term used to describe a situation where one person sends a message to another person on Snapchat, and the recipient reads the message but does not respond. This is indicated by a grey emoji beside the message instead of the usual blue or red. The sender is left wondering why the recipient did not respond to their message. This can cause frustration and confusion in relationships or friendships. Some people deliberately leave messages on read as a way of ignoring someone or showing disinterest. Others may forget to respond or may be too busy to respond at the time.
