Haven't used the app in over a year. Opened it and it asked to be updated. I did so. Now I'm unable to make or receive voice and video calls. Checked about a week later and a new update was available which I did. Yet I still don't have the option to make or receive a voice or video call. Updates should get more features not loose old ones. Persistent on both updates... If developers can't correct these features makes me wonder how much of our data is might also be mishandled or unprotected...
