Meta's popular chatting app WhatsApp is being used by every second smartphone user today. For some users, WhatsApp is also connected to their office work. Many times the double blue tick is not visible when a message is sent. However, there is always a doubt about the blue tick. In such a situation, it is important to know what the company has to say about WhatsApp read receipt-

The company clarifies some things regarding read receipts on WhatsApp-

If the phone of the user receiving the WhatsApp message is turned off and the message has not reached any other device linked to his phone, then the second checkmark will not be visible.

The second checkmark will appear on the group chat only when all the people in the group receive the message. For a double blue tick, it will be necessary for all the users to have read the message.

The read receipt will be reset upon editing the message. You can check which people have seen your update.
If the clock icon appears instead of the tick with the message, it means that the message has not been delivered or sent. This can happen due to connectivity issues.

If you are not able to see the blue check mark, or blue microphone on your message after sending a WhatsApp message, then there can be many reasons for this -

You or the message receiver may have disabled the read receipt.
The WhatsApp user to whom you are sending the message may have blocked you.
The WhatsApp user to whom you are sending the message may not have read the message.
You or the WhatsApp user receiving the message may have a connection issue.
If you are sending a message to a user for the first time, then the read receipt is missed.
The date-time setting in your or the message receiver's phone may be incorrect.
