content: The app generally works well. My biggest gripe is that it shows the mic on the screen as a status indicator but tapping it doesnt toggle. You have to tap wait for the command bar to display then tap the mic. On a few occasions Ive been muted and unable to get the bar to show so that I could unmute myself and talk. So I tend to tap the screen habitually throughout calls to make sure its still responding and able to be changed.
