I’ve noticed this, too. Particularly frustrating when a station is created from a song. Indicating thumbs down would help build a better station based on songs I like and those I don’t. I can only hope that if I skip a song it serves the same purpose as giving it a thumbs down but confirmation would be appreciated Sonos  :)   If that’s not the case, please bring thumbs up/down or at least thumbs down back asap!
