Dh asked me to reply to my sister on his phone as he was driving. She switches between text and WhatsApp even between conversations lol but i think it was text. Sent said message and pressed back so it went to the list of messages. One said blocked user ? Is this some he has blocked no messages were there it was just a page that looked like a conversation but no messages and blocked user as the contact name. I have I phone so not sure what this is all about
