I love the release radar suggestions and i'm listening to them every week.
I experience the following problem regularly. When I dislike a song on one device, that is not synchonized to my other devices like tablet or desktop. On them it still looks, like i didn't do anything. Same is if i use bluetooth audio devices or not - that seems to count as a separate device.
When i'm playing music via Google Home device and i dislike a track on my smartphone, the song does not get skipped as it usually does when playing only on my smartphone or desktop.
