However, there is a bug in iOS operating system which breaks UnbornHeart application in newer iPhone 8, iPhone 8 plus and iPhone X models. The application is not receiving audio data through the adapter anymore. Unfortunately, we can't fix the problem in our application but it needs to be fixed by Apple. We have reported the problem to Apple and are waiting for their actions.
We are really sorry for this problem. Unfortunately, we can't do anything but wait for Apple at the moment.
