The "floating notifications" (are they the same as "Heads Up"?) will not turn off (I have them disabled and they still appear). The main issue is that when a text arrives, it will sound the notification, but then blocks whatever audio was playing until I clear it (X). Also, the 'reply' feature does not appear to work -- or does it only turn on the microphone?
