With the previous update, I would swipe up on the podcast artwork, while it was playing, and the sleep timer button was under there, along with the animation of a reel-to-reel tape playing. With this one, I can't swipe up. Is it somewhere else?
The reel to reel graphic was removed, but everything else is the same. Tap on the podcast artwork to bring up the scrubber for the podcast that is playing. The sleep timer option is in the center directly below the scrubber at the top.
