Warning notification stops music

Hello Line of action team and happy holidays!
Im out of home right now and i needed to practice on my phone yesterday but i noticed that when the notification goes off to notify for "5 sec left" makes the music apps to stop playing . I believe it needs a mute button or a way to make the music continue. 
Anyway that's all :D

So we don't send any signals that explicitly stop music apps, but some devices will take a sound from one app and instead of playing it in addition to other noises, it just stops all other noises. If this is your device, you can turn the warning sounds off! Go to settings (The cog icon at the bottom) and uncheck "play warning sounds when the pose timer gets low"
