What does one gray checkmark on WhatsApp mean - in detail?
A single gray checkmark on WhatsApp signifies that your message has been successfully sent from your device to the WhatsApp servers, but it has not yet been delivered to the recipient's phone. This means that the message is currently in transit and has not reached its final destination. The gray checkmark serves as an initial indicator that your message has left your device and is on its way to the recipient. Once the message is successfully delivered to the recipient's phone, the checkmarks will turn blue, indicating that the message has been read by the recipient. If the checkmarks remain gray for an extended period, it could indicate a connectivity issue or the recipient's device being offline.
