An attentive superuser (Thanks Laurin!) in the German community noticed differences in iOS versions 9.27, 9.28 and 9.29.
With 9.28, the menu that appears as soon as you click on the angry emoji in the flow has been revised.
9.27 and earlier versions:
9.28 and newer:
The new “Change the style” option takes you straight to a completely different genre.
With the recently released 9.29 (currently beta), the player has been cleaned up a bit.
9.28 and older:
9.29 and newer:
The sleep timer has been completely removed. Don't worry, the timer has been removed for flow playback only. This is where the evil emoji can be found.
If you listen to playlists, albums, etc., the timer can of course be found in the familiar place.
