My Question or Issue

I have run the entire troubleshooting gauntlet.  The Spotify app works just fine when I listen directly on my phone.  It works just fine when I use the Spotify app to cast to my PS4.  It also works fine when I use the Google Home app to mirror my phone's audio to my (various) Google Home speakers.

However, when I use the Spotify app to connect to ANY of my Google Home speakers, playback stops after about ten seconds, and proceeds to skip an arbitrary number of times, tries to play again, but fails after ten seconds to repeat the process.  The only exception is the ads.  They play just fine.

Corrective actions that I have taken:  

I have unlinked/relinked my spotify account in the Home app

I have rebooted all my devices

I have uninstalled/reinstalled the Spotify app

I have factory reset all my devices.

This has been an ongoing issue for some time, and was a contributing factor to me stepping down to the free service.  I'm at my wit's end, and would really like this resolved... or at least get some useful advice for a change.
