Android 13 update causing issues with lock-screen and menu "miniplayer"

Since updating to Android 13 on a Pixel 4a 5G I am having issues with the miniplayer functionality. It will only appear on the lockscreen or in the drag down menu if I resume playback from within the app itself (widget will resume playback, but will not spawn the miniplayer). The miniplayer will then disappear at some point - I have not identified a cause or timeframe that is consistent, but this behaviour started immediately after completing the update which seems to have also updated the miniplayer appearance.

I haven’t spotted any current topics for this and the troubleshooting that I saw for some of the Android 12 issues hasn’t worked.

I have not seen this behavior since upgrading to Android 13. If the “miniplayer” is not on the lockscreen or notification drawer, resuming playback from the widget makes it appear.

Have the same issue with Pixel 6 pro Android 13 and latest update
