BTW, coming back here after a couple years, I'm sorry to hear people are
still dealing with this.I, for one, had not had this issue since running
the steps above - across 2 homes with added google devices. So please
try these steps if you haven't yet...
So I've had this fixed for a few months now - and wanted to re-share how
I fixed it.First thing, for context: casting or using the Google
Assistant to initiate streaming are not really different. It's just a
matter of how the streaming is initiated. ...
Quick update:Still no ads today after doing the above on the speakers
that were playing ads previously. I've started playback via the YTM app
and via Google Assistant to the same speakers. I'll try to test with my
other speakers in the house to see i...
Yeah - my theory is that one of your speakers (other than "Living Room")
lost the credentials that allowed it to access YTM as a Premium user -
and that would prevent the whole group from streaming as Premium.
Those are (were) my symptoms. And only on certain google devices - which
is what led me to the idea of the credentials for the Premium account
being lost on particular devices.
