What does one tick mean in a WhatsApp message - in detail?
A single tick in a WhatsApp message is an indicator used to convey the status of message delivery. When you send a message on WhatsApp, the absence of any ticks next to your message signifies that it has not yet been delivered to the recipient's device. Once the message leaves your phone and reaches WhatsApp's servers, one grey tick appears beside the message. This tick indicates that WhatsApp has successfully transmitted your message to the recipient's device, but it does not guarantee that the recipient has seen or read the message. The single grey tick serves as a preliminary confirmation of delivery, providing reassurance that the message is on its way to the intended recipient.
