According to shares on social media, people listening to podcasts on YouTube Music will see a new UI. This is still in the process of being rolled out, so you may not see it yet. The changes include:
A basic “Now Playing” UI: The previous and next track buttons will be replaced with rewind 10 seconds and fast forward 30 seconds buttons.
On the far left of the screen, you’ll see a speed control button. Its speed ranges from .25x to 2x in increments of .25x.
On the far right of the screen, you’ll see a sleep timer.
The “Lyrics” button on the bottom bar will be replaced with an “Info” button. When you click this button, you’ll see all of the podcast’s content description.
On the “Info” page, you’ll find a play button as well as options for adding bookmarks to your podcast.
When there is something queued up next to play, it will display your upcoming podcast queue.
