My friend connects with me via the Facebook Messenger application.  A few days ago, after it was turned off, she checked if she had messages from me and found out that I was online Active now many times.There is no way that I was online because I closed all of my applications when I work and had been in meetings (although my phones were, in fact, offline). Can anyone explain why the app lists me as being online and active?
