Music keeps playing on simcity buildit even though music is disabled

What’s with the build sound  that plays even though all game sounds are turned off. Now  it’s bleeding over to my Sims Mobile game and again sound is turned off. I have to keep turning  my IPad off and on to get it to eventually stop. And now when I watch the Ads I’m being returned to Apple Apps with no way to get back to game and then I’m  subject to losing my reward or that noise start up again. What have y’all done? Fix it please.
