Two blue ticks in the end of your message
indicate that the recipient has checked
your message. Here’s how to
find out who has read your WhatsApp message in
group chats:
For Android users
Long-press on the message sent by you to uncover an ‘i’ icon – tap it to check who has received and read your message.
For iPhone users
Open a chat with any contact or group to see the ‘Message Info’ screen –
swipe the message from left to right to check delivery and read
notifications.
