With the following sequence of actions, beyondpod seems to "desynchronize" from my Google Home.

1. Cast from BP to GH (using Pixel)
2. Minimize BP on Pixel
3. Do something else on Pixel for a bit, say read the Twitter app for 2 minutes.
4. Deminimize BP
5. BP is where it was about 2 minutes ago, and the sound playing on GH immediately synchs with that location, so i hear that couple minutes again.
