On WhatsApp, I can see my friend's last seen on 20/05/15 at 14:15. I can't see him online so I sent him a message only had 1 tick and his last seen did not update. I spoke to him and he said he's not got my messages. What could it be?
"As I chat with my husband on WhatsApp, I never see him go from ""online"" to ""typing"" and when he is replying it shows him offline. After I receive his messages, it shows him back ""online"". How is this possible?"
