Swapping layout will throw you back to the first song in the ”swiping session”

If you have scrolled past a few songs in either layout (Stack or Vertical), and click on Settings → Layout & Content and swap layout, and go back to Discovery.

You will be thrown back to the first song of that swiping session.

The song that was playing before you swapped layout will still be playing, but you will instead see the first song you could swipe.
