On WhatsApp , it says on the message info that the message has been read with 2 blue ticks and no time and message delivered with 2 grey checks with time . What does this mean ?
My friend is abroad and I have sent him messages . There is one grey tick next to the messages I recently sent , but when I swipe left it says read with 2 blue ticks but no time of read . How can I know if he has seen my messages ?
