What is left on delivered?

"Left on delivered" refers to a feature available in some messaging apps, where a user can see whether their message has been delivered to the recipient's device but hasn't been read or opened yet. This feature is commonly found in apps like WhatsApp and Facebook Messenger.

When a message is sent, it first shows a single grey checkmark indicating that the message has been sent. Once the message reaches the recipient's device and is successfully delivered, the grey checkmark turns into a double grey checkmark, indicating the message has been delivered. If the recipient has not yet opened or read the message, the status will show as "left on delivered."

This feature can be helpful to determine if the recipient has received the message, but it's important to keep in mind that the recipient may not have seen or read the message yet, even if it shows as delivered. It's also important to respect someone's privacy and not constantly message or pester them if they haven't responded.
