Hello Friends! I'm using Microsoft Lumia 640XL (INDIA). Friends my query is related to Facebook Messenger. Recently I updated Messenger app, after completion of update when I launched messenger app for 1st time it showed a new features that is *Voice Call & Video Call* feature and it was also working properly; but after some time when I again launched the messenger app, features where disabled, there were no voice call and video call ICONS visible. Can any one pls help me to know what's the issue? Thanks in advance
