When playing podcasts via Bluetooth AND podcast speed is NOT 1x (I usually listen at 1.25x, but have tried other speeds), the Spotify app will not pause when the Play/Pause button on the headphones is depressed. Play works fine. If I set the speed to 1x, Pause works fine. With my wired (Beats urBeats 3) headset, all buttons work normally at all speeds. Just my Sony WI-C400 headphones.
