A small percentage of users now get revamped classical radio. Try it here: https://play.spotify.com/radio/genre/classical Use the skip button to flip through a few tracks.
If you only see soundtracks and greatest hits from not-so-great compilations and less than 10 composers, you are still on the old radio. Please ignore it like you did in the past few years.
If you see a wide range of selections from respectable labels, then play on. The more you listen, the more users will get the new version.
Your feedback will be much appreciated. Thanks.
