Stops playing when app is opened

This has been a problem seemingly ever since the newest iOS update or maybe it’s the app... something isn’t right. When I’m playing music in the app (especially streaming a radio) and I open the google play app, the music stops playing even though it shows that it’s not paused. So if I go like a song that’s playing it stops and I have to hit the pause button and then play again to get it to continue playing.
