If the last visit time is not displayed in WhatsApp, what does that mean - in detail?

If the last visit time is not displayed in WhatsApp, it typically indicates that the user has adjusted their privacy settings to restrict this information from being visible. This feature, known as "Read Receipts," allows users to control whether others can see when they have read a message or not. When enabled, a double checkmark appears next to the message, indicating that it has been delivered and read. However, if the user has turned off Read Receipts, the second checkmark (indicating the message has been read) will not appear, and the last visit time will not be displayed. This setting is designed to provide users with more control over their privacy and communication experience on the platform.
