iphone messenger: showing when a person was last online
So, underneath the persons name, sometimes it shows you when they were last online. i.e. Online Now, Active 2 min. ago, Active 5 hrs. ago.
Sometimes it doesn't show anything. Can you tell me why sometimes it doesn't tell me when they were last online? Is there a time cut-off? For example, if they haven't been online for 6 hours or longer, it doesn't show anything under their name? Any help you can offer would be appreciated.
