WHY DON'T AIRPLAY WORK ANYMORE FOR WINDOWS 10 APP, REFLECTOR?

- AIRPLAY USE TO WORK FOR MY WINDOWS 10 APP CALLED REFLECTOR. THIS APP MIRRORS THE IPHONE SCREEN. BUT, AFTER THE NEW UPDATE TO IOS 10, WHEN USING THE IPHONE AIRPLAY MIRRORING IT'S NOT SHOW THE REFLECTOR APP. ALL ITS SHOWING IS (LOOKING FOR APPLE TV).

- ALSO WHERE DO I GO TO WRITE AN EMAIL TO APPLE ABOUT THIS PROBLEM?
