Facebook chat solution! Anyone?

Its definitely problem with Microsoft and WP.

I had this problem on my 820 quite often like skipping messages and not showing up any notification/updating tile when someone chats etc.
Sometimes it just doesn't connect to chat as well.At one point , "Me" Tile got messed up.I can post an update without problem but cannot use "check-in" , but after 2 days it got fixed by itself though.

I never had any problem with integrated FB on iOS 6/7 on iPad or Galaxy S4 (4.2.x).They both show every notification almost instantaneously .Never faced any bugs or missing notifications.

Having used all 3 OS for more than 6 months minimum each , This problem solely lies in the fact that API's/Server access seem to be messed up on WP.
 
It seems that it is fixed now by GDR3 - thanks Microsoft, it is really better late as never :)
 
there's no way to use faebook group chats in the native messaging hub. I don't like having to go to the facebook app just for group chats. it'd be much more streamlined if everything can be done thru the messaging hub.
 
I too had the same probem, i couldnt connect it neither on wi-fi nor 3G. All you need to do is remove any other chatting software (whats app, skype etc).
