We are using lineworks as a mode of communication on our company. Then suddenly one day there was a complain from one of the users. The lineworks notification was not functioning on IOS mobiles. I make a test for that problem. 1. I make call - But there was no notification that I was calling. 2. I message - But there was no notification that I make a message. The only way that I can see is that when I open the conversation. Then it was just missed call. I hope someone can help me on this matter.
