Live Chat not showing online friends

Hi Team,

Is there any bug with live chat widget as on v12 & v11 its not showing online friends.  How do I install chat support?  

I am able to directly search friends and message them but they are not shown on my online friends list. 

Screenshot 1: No Online Friends Seen

Screenshot 2: Friends are visible if I search for them with their online status

I want my friends to be visible on the list directly without me searching for them. Is there anything to enable or fix to get it working?
