Great reply; thanks for the comment. I had forgotten about using the app for volume control, so I just now played with this feature again. I started a TuneIn station from my list of Favorite stations in the TuneIn section of app. I had the volume level display. I told Alexa "volume up one", volume went up and slider on app moved a notch up, tried volume down, and slider moved back to previous position. Told Alexa "volume zero" and slider was at bottom, then told it go to volume level I wanted which was "volume level 3". Move slider with finger and the volume level changes and displays a number; just tap slider to see the volume level number. Very handy for a visual indication of volume level and for controlling it from a distance and without out any verbal command. Play with it and find other things you can do in here.
