PSN online game lobbies friends list issues

We are a forum based community that enjoys the online gaming experiance that we share via the Playstation Network (PSN). At present however there is an issue with the online games lobbies friends lists not refreshing meaning that you cannot invite friends to play online if they sign in after you.
We know of four games that this effects so far but it may be more, these games are COD4, Warhawk, GTA4 and Everybodys Golf World Tour. If you have experianced this problem with any of the above games or any other game titles played via the PSN then please add your name to the pettion and give us a stronger voice to force SONY into action to resolve this problem. Thank you for your time.
