It's impossible to get calls with this app. If I get called I can answer the displayed call and it shows a connection only on my side but it doesn't connect on the other side, then the call disconnects and a second "ghost call" comes in after a few seconds even if the caller didn't start another call. If I call the other person everything works fine. With this bug that exists for more than a month now it's possible to get in contact with me, I always have to call back.
