Media Player Integration no longer supports Google Cast states?

A few months ago, if I play music on a Google Home device of mine (Mini, Display devices, etc); I used to be able to see state information about what media / song / etc was actively playing. Now it says off / paused / etc.

For example; a Google Nest display hub in my kitchen:

media_player.kitchen.display

If I were to stream Spotify songs; I could see state information (playing) plus information about the media itself. Now all of my devices are empty with no information. Removing and re-adding the integration does nothing. The devices are removed and re-added; yet exhibit the same behavior.

Did something change on Google’s end / HA that makes this no longer possible? Or did I inadvertantly break something?

I DID add the Spotify integration, and I can see the information about media playing with THAT entity (media_player.spotify_player). But my Google / Nest speakers and displays now give me nothing.
