If you turn off the internet and go into WhatsApp, will it be seen that you have read the message - briefly?
If you turn off the internet before opening WhatsApp, your messages will not mark as read. This ensures that the sender does not see the blue checkmarks indicating that you have viewed their message.
If you turn off the internet and go into WhatsApp, will it be seen that you have read the message - in detail?
If you turn off the internet and open WhatsApp, the status of your messages will not change to "read" for the sender. This is because WhatsApp requires an active internet connection to update the delivery and read statuses of messages. When you are offline, WhatsApp cannot send or receive updates about message statuses, including whether a message has been delivered or read. Therefore, even if you open the chat and view the message while offline, the sender will not see that their message has been read until you reconnect to the internet and WhatsApp is able to synchronize your message status with its servers. It's important to note that this applies only to the delivery and read receipts; if you respond to a message while offline, your response will be sent automatically once you regain an internet connection.
