Norton Safety Minder

I have Norton Safety Minder set up on a laptop that my son uses.  I normaly keep a check on his activity from a different laptop through the Safety Minder website.  Why can't I see current up to the minute activity through the website?  Example:  When I checked the website it showed that the last time he was on was last night at 11:00pm.  I know he's been on several times today and is currenty on at 8:31 p.m. tonight, but I can't see it.  Can anyone tell me why and if the settings can be changed to show current up to the minute information.

 

Thank you
