iPhone group calls still not working properly after FaceTime bug update

Group FaceTime calls on the iPhone and other Apple products are still not working properly, after the company rushed to fix a major bug. Earlier this month, it emerged that it was possible to listen in on people through their iPhone by exploiting a bug in FaceTime, the app used to make audio and video calls over the internet. By adding someone into a group conversation, their phone would start ringing – and during that entire time, the microphone would be switched on and allow the caller to hear everything a person was doing. Apple rushed to fix that bug, first by switching off the service entirely and then pushing out a software update that stopped it happening. But that update has still left some problems and the calls are not working entirely since the update was released.
