In what case is there one checkmark in WhatsApp - in detail?
In WhatsApp, a single checkmark appears next to a message when it has been successfully sent from the user's device but has not yet been delivered to the recipient's device. This status indicates that the message has left the sender's phone and is currently in transit through the internet or mobile network infrastructure. It does not guarantee that the recipient will receive the message, as there could be various factors affecting delivery, such as connectivity issues or the recipient's phone being turned off. Once the message is successfully delivered to the recipient's device, WhatsApp displays two checkmarks next to the message, signifying successful delivery. If the recipient has read the message, a blue background will appear around the two checkmarks, indicating that the message has been seen. Understanding these status indicators helps users gauge the current state of their messages and anticipate when they might expect a response from the recipients.
