Game blocking other sound
I play on an apple, and in an update that came out a few weeks ago the game stops all other sounds when it's open.
This is really annoying, especially if you leave the game open while walking but want to listen to something else too.
Having played every other Niantic game, none of them stop other sounds.
Please don't block other sounds. I like to listen to music or podcasts when I walk, and this means I leave the game open - it stops me wanting to open the game at all!
