Music Controls Sort of Work

I've owned my Instinct for about 4 months now and I've just gotten around to trying out the Music Control.  I start a playlist on my phone using the Amazon Music app.  I open the Music Control page on the Instinct.  The Play/Pause feature works.  The Next & Previous Track works.

What doesn't work:

  1. I can't decrease the volume, increasing the volume functions correctly
  2. The volume adjust bar (looks like a vertical progress bar) looks like it should show the volume setting, but is always "empty".
  3. There is a what looks like a track time indicator on the page, but always reads 0:00 even when a track is playing

Using a Samsung Galaxy A10 and Instinct version 6.91 beta.

Anybody seeing these issues?

Thanks
